What is the minimum legal age for marriage for males under the Mizo Marriage, Divorce and Inheritance of Property Act, 2014?
A)
18 years
B)
19 years
C)
21 years
D)
20 years
Under the Mizo Marriage, Divorce and Inheritance of Property Act, 2014, the law specifies the minimum legal age for marriage to ensure the maturity and consent of the parties involved. In alignment with general Indian legal standards for marriage (such as those found in the Special Marriage Act and the Prohibition of Child Marriage Act), the Act stipulates that the minimum legal age for a male to enter into a valid marriage is 21 years. Option (a) 18 years is typically the minimum age for females; options (b) 19 years and (d) 20 years are not the legal thresholds defined for males under this specific legislation.

Who has the authority to dissolve a Village Council before the end of its term?
A)
Village Elders
B)
Deputy Commissioner
C)
Governor of Mizoram
D)
President of India
Under the Lushai Hills (Village Councils) Act, 1953, the administration and oversight of Village Councils are vested in the district administration. Specifically, the Deputy Commissioner (DC) is empowered to dissolve a Village Council before the expiration of its term if it is found that the Council is acting against the interests of the village, failing to perform its duties, or if there is a breakdown of constitutional machinery at the village level.
- Option (a) Village Elders: While they hold traditional respect, they do not possess the legal statutory authority to dissolve a legally constituted Council.
- Option (c) Governor of Mizoram: The Governor is the constitutional head of the state, but the operational management of Village Councils is delegated to the district administration.
- Option (d) President of India: The President's powers are at the national/state level and do not extend to the dissolution of local village-level bodies under this specific Act.

Who conducts the elections to the Village Councils under the Act?
A)
Deputy Commissioner
B)
State Election Commission
C)
Village Elders
D)
Sub-Divisional Officer
Under the Lushai Hills (Village Councils) Act, 1953, the administration and oversight of Village Councils are vested in the district administration. Specifically, the Deputy Commissioner (DC) is the designated authority responsible for the conduct of elections to the Village Councils. The DC ensures that the electoral process is carried out according to the rules prescribed under the Act.
Why other options are incorrect:
- b. State Election Commission: While the SEC handles general local body elections in many Indian states, the specific framework of the 1953 Act for Lushai Hills assigns this duty to the DC.
- c. Village Elders: While elders may have traditional influence, they do not have the legal statutory authority to conduct official elections under the Act.
- d. Sub-Divisional Officer: The SDO may assist in the process or act as a returning officer in some capacities, but the primary authority responsible for conducting the elections under the Act is the Deputy Commissioner.

What is the first step in the recovery process of a public demand under the Act?
A)
Issuance of a certificate
B)
Attachment of property
C)
Filing a civil suit
D)
Publication of a notice
Under the Mizoram Public Demands Recovery Act, 2001, the recovery process begins with the 'Certificate' stage. The Collector (or an authorized officer) first issues a certificate stating that a certain sum of money is due to the government or a public officer. This certificate serves as the formal legal instrument that initiates the recovery proceedings. Once the certificate is filed and served, the recovery officer can then proceed to subsequent steps such as the attachment of property or sale of assets if the demand remains unpaid. Filing a civil suit is generally bypassed by this Act to provide a faster administrative recovery mechanism, and publication of notice typically follows the issuance and service of the certificate.

What is the minimum age for a person to contest in Village Council elections?
A)
18 years
B)
35 years
C)
25 years
D)
21 years
Under the Lushai Hills (Village Councils) Act, 1953, the eligibility criteria for a person to be elected as a member of the Village Council are specified. According to the Act, a person is eligible to contest the election if they are a registered voter of the village and have attained the minimum age of 25 years.
- Option (a) 18 years is the minimum age to be a voter (elector), not a candidate.
- Option (b) 35 years is typically the minimum age for higher constitutional offices (like the President of India), not for Village Councils.
- Option (d) 21 years is a common age requirement for certain local body elections in other jurisdictions, but not for the Village Council under this specific Act.

The principle of restitution is embodied in which provision of CPC?
A)
Section 144
B)
Section 148
C)
Section 151
D)
Section 152
The principle of restitution is embodied in Section 144 of the Code of Civil Procedure (CPC), 1908. Restitution is based on the equitable maxim 'actus curiae neminem gravabit' (an act of the court shall prejudice no one). It ensures that if a party has received a benefit under a decree that is subsequently reversed or modified by a higher court, the party is restored to the position they would have occupied had the original decree not been passed.
Analysis of other options:
- Section 148: Deals with the enlargement of time for doing any act prescribed by the Code.
- Section 151: Deals with the 'Inherent Powers' of the Court to make such orders as may be necessary for the ends of justice or to prevent abuse of the process of the Court.
- Section 152: Deals with the correction of clerical or arithmetical mistakes in judgments, decrees, or orders.

What is the procedure for obtaining a Regular Inner Line Permit (ILP) in Mizoram?
A)
Apply directly to the Ministry of Home Affairs
B)
Submit an application to the Deputy Commissioner with necessary documents
C)
Obtain from Liaison Officers in specified cities
D)
Apply online through the Ministry of External Affairs
The Inner Line Permit (ILP) is a travel document required for Indian citizens from other states to enter Mizoram, as per the Bengal Eastern Frontier Regulation, 1873. For a Regular ILP, the standard administrative procedure involves submitting an application along with supporting documents (such as identity proof and address proof) to the Deputy Commissioner (DC) of the concerned district in Mizoram or the designated authority. While Temporary ILPs can be obtained at entry points or through Liaison Officers in cities like Guwahati or Silchar, the formal process for a Regular permit is handled by the district administration (Deputy Commissioner). Option (a) and (d) are incorrect because the Ministry of Home Affairs sets the policy, but the issuance is decentralized to the state/district level, and the Ministry of External Affairs handles passports/visas for foreign nationals, not ILPs for domestic travel.

Which of the following is not a ground for divorce under the Mizo Marriage, Divorce and Inheritance of Property Act 2014?
A)
Kawngka sula mak
B)
Sum chhuah
C)
Mak
D)
Falak
Under the Mizo Marriage, Divorce and Inheritance of Property Act, 2014, the law recognizes specific traditional and legal grounds for the dissolution of marriage.
1. 'Mak' (Adultery) is a recognized ground for divorce.
2. 'Falak' (Desertion/Abandonment) is a recognized ground for divorce.
3. 'Sum chhuah' (Payment of compensation/settlement for divorce) refers to the traditional process of settling a divorce through financial means, which is recognized under the customary laws integrated into the Act.
'Kawngka sula mak' is not a legally defined ground for divorce under the provisions of the 2014 Act. While it may be a colloquial term or a specific social scenario, it does not constitute a statutory ground for seeking a decree of divorce in a court of law under this specific Act.

The marriage price paid by the bridegroom and received by the head of the bride’s family is known as:
A)
Man
B)
Mantang
C)
Sumfang
D)
Thutphah
Under the Mizo Marriage, Divorce and Inheritance of Property Act, 2014, and traditional Mizo customary law, 'Mantang' refers to the marriage price (bride price) paid by the groom or his family to the bride's family (specifically the head of the family) as a token of respect and as a formal requirement for the marriage.
Analysis of other options:
- 'Man' is a general term for price or value, but not the specific legal/cultural term for marriage price.
- 'Sumfang' generally refers to a fine or a penalty paid in customary law.
- 'Thutphah' refers to a will or a testamentary disposition of property, not a marriage payment.
MCS Departmental • 2025 • Paper-III
Under the Mizoram Public Demands Recovery Act, 2001, who is designated as the Certificate Officer responsible for recovery proceedings?
A)
District Magistrate
B)
Sub-Divisional Officer (S.D.O.)
C)
Revenue Officer
D)
Chief Secretary
Under the Mizoram Public Demands Recovery Act, 2001, the authority responsible for the recovery of public demands is the Certificate Officer. According to the administrative framework of the Act, the State Government appoints the Certificate Officer, and typically, the Sub-Divisional Officer (S.D.O.) of the respective subdivision is designated as the Certificate Officer to execute the recovery proceedings, issue certificates, and oversee the attachment or sale of property to recover dues. While the District Magistrate (a) holds overall administrative control, the specific statutory role of the 'Certificate Officer' for the purpose of these proceedings is vested in the S.D.O. Revenue Officers (c) may assist, and the Chief Secretary (d) is a policy-level administrative head and not an executing officer for individual recovery certificates.
MCS Departmental • 2025 • Paper-III
Who is empowered to issue a certificate for recovery of public demand under Section 4?
A)
District Magistrate
B)
Deputy Commissioner
C)
Certificate Officer
D)
Chief Secretary
Under the Mizoram Public Demands Recovery Act, 2001, Section 4 specifically deals with the recovery of public demands. According to the statutory provisions of the Act, when a public demand is due, the 'Certificate Officer' is the designated authority empowered to file a certificate for the recovery of the said demand. While the government may appoint specific officials (such as a Deputy Commissioner) to act as a Certificate Officer, the legal authority and the power to issue the certificate are vested in the role of the 'Certificate Officer' as defined by the Act. Therefore, option (c) is the most accurate legal answer, as it refers to the specific statutory designation empowered by Section 4.

What is the primary purpose of the Mizoram Municipalities Act, 2007?
A)
To regulate rural development
B)
To establish municipalities for urban governance
C)
To manage forest resources
D)
To control agricultural practices
The Mizoram Municipalities Act, 2007 was enacted to provide for the constitution and management of municipalities in the state of Mizoram. Its primary objective is to implement urban local self-governance, allowing urban areas to manage their own civic administration, infrastructure, and public services.
Analysis of options:
- Option (a) is incorrect because rural development is governed by the Mizoram Village Councils/Act and Panchayati Raj frameworks, not the Municipalities Act.
- Option (b) is correct as the Act specifically deals with the creation and regulation of municipal bodies for urban areas.
- Option (c) is incorrect because forest resources are managed under the Forest Act and the Department of Forests & Environment.
- Option (d) is incorrect because agricultural practices are managed by the Department of Agriculture and related land laws, not by urban municipal bodies.
MCS Departmental • 2025 • Paper-III
Under the Act, which of the following is a judicial function of the Village Council?
A)
Approving construction of roads
B)
Settling local disputes among villagers
C)
Issuing birth and death certificates
D)
Collecting village taxes
The Lushai Hills (Village Councils) Act, 1953, empowers the Village Council to act as a local administrative and quasi-judicial body. A 'judicial function' refers to the power to hear disputes, interpret local customs/rules, and provide resolutions or judgments. Settling local disputes among villagers is a core judicial function of the Council, allowing for the resolution of conflicts at the grassroots level before they escalate to higher courts.
Why other options are incorrect:
- Option (a) 'Approving construction of roads' is an administrative or developmental function.
- Option (c) 'Issuing birth and death certificates' is a clerical or registration function.
- Option (d) 'Collecting village taxes' is a fiscal or revenue-related administrative function.

A civil court may stay the execution of a decree under which provision?
A)
Section 115
B)
Order XXI Rule 26
C)
Section 151
D)
Order I Rule 10
Step-by-step reasoning:
1. The question asks for the provision under which a civil court may stay the execution of a decree.
2. Order XXI of the Code of Civil Procedure (CPC) deals specifically with the 'Execution of Decrees and Orders'.
3. Order XXI Rule 26 explicitly empowers the court to stay the execution of a decree for a reasonable time, whether such stay is granted for a sufficient cause shown or to allow the judgment-debtor to apply for an appeal or other legal remedy.
4. Analysis of other options:
- Section 115: Relates to the 'Revision' power of the High Court, not the general stay of execution by a civil court.
- Section 151: Relates to the 'Inherent Powers' of the court. While inherent powers can be used in extreme cases, there is a specific provision (Order XXI Rule 26) for staying execution.
- Order I Rule 10: Relates to the 'Suit in name of wrong plaintiff' or 'Striking out or adding parties', which has nothing to do with the execution of a decree.
Therefore, Order XXI Rule 26 is the specific and correct provision.
MCS Departmental • 2025 • Paper-III
The object of the rule of res sub judice under Section 10 CPC is to:
A)
Avoid conflicting decisions
B)
Enable appellate review
C)
Protect judicial independence
D)
Grant interim relief
Section 10 of the Code of Civil Procedure (CPC), 1908, deals with the doctrine of 'Res Sub Judice' (meaning 'under judgment'). This rule mandates that a court shall not proceed with the trial of any suit in which the matter in issue is also directly and substantially in issue in a previously instituted suit between the same parties.
1. Why Option (a) is correct: The primary objective of Section 10 is to prevent courts of concurrent jurisdiction from simultaneously trying two parallel suits in respect of the same cause of action. This prevents the possibility of two different courts delivering contradictory or conflicting judgments on the same matter, which would lead to legal chaos and uncertainty.
2. Why Option (b) is incorrect: Appellate review is a process where a higher court reviews the decision of a lower court; it is not the purpose of staying a trial under Res Sub Judice.
3. Why Option (c) is incorrect: Judicial independence refers to the ability of judges to decide cases based on law without external pressure; it is a constitutional principle, not the objective of Section 10.
4. Why Option (d) is incorrect: Interim relief (like temporary injunctions) is granted to preserve the status quo during a trial; Section 10 is about staying the trial itself, not granting relief.
MCS Departmental • 2025 • Paper-III
A suit is said to be res sub judice under Section 10 of CPC when:
A)
It has already been decided by a competent court
B)
It is pending before another court between the same parties and on the same matter
C)
It involves a criminal case also
D)
The suit relates to different reliefs
Section 10 of the Code of Civil Procedure (CPC), 1908, deals with the doctrine of 'Res Sub Judice' (meaning 'under judgment'). The purpose of this section is to prevent courts of concurrent jurisdiction from simultaneously trying two parallel suits in respect of the same matter in issue, thereby avoiding conflicting decisions and protecting the defendant from harassment.
For a suit to be stayed under Section 10, the following conditions must be met:
1. There must be two suits—one previously instituted and one subsequently instituted.
2. The matter in issue in the subsequent suit must be directly and substantially the same as in the previous suit.
3. Both suits must be between the same parties or their representatives.
4. The previous suit must be pending in the same court or any other court in India (or a court established by the Central Government outside India).
5. The court where the first suit is pending must be competent to grant the relief claimed in the second suit.
Analysis of other options:
- Option (a) describes 'Res Judicata' (Section 11), where a matter has already been decided.
- Option (c) is irrelevant, as Section 10 applies specifically to civil suits.
- Option (d) is incorrect because for Res Sub Judice to apply, the 'matter in issue' must be the same, regardless of whether the reliefs sought are identical or slightly different, provided the core issue is the same.
MCS Departmental • 2025 • Paper-III
Which of the following is a condition precedent for execution of a decree under CPC?
A)
Consent of parties
B)
Entry of decree in the register
C)
Application for execution
D)
Appeal against the decree
Under the Code of Civil Procedure (CPC), a court does not automatically execute a decree once it is passed. The decree-holder must initiate the process by filing an 'Application for Execution' under Order XXI. This application is the essential condition precedent that triggers the court's machinery to enforce the judgment.
Why other options are incorrect:
- (a) Consent of parties: Execution is a legal right of the decree-holder to enforce a court order; it does not require the consent of the judgment-debtor.
- (b) Entry of decree in the register: While administrative records are maintained, the formal trigger for the execution process is the application, not the mere act of registration.
- (d) Appeal against the decree: An appeal is a remedy to challenge a decree. While a stay of execution may be granted during an appeal, the filing of an appeal is not a 'condition precedent' for execution; in fact, execution can often proceed unless a stay order is specifically granted by the appellate court.
MCS Departmental • 2025 • Paper-III
Which provision under CPC governs the territorial jurisdiction of civil courts?
A)
Section 9
B)
Section 15
C)
Section 10
D)
Section 144
Step-by-step reasoning:
1. Analysis of Section 15: Section 15 of the Code of Civil Procedure (CPC) explicitly states that 'Every suit shall be instituted in the Court of the lowest grade competent to try it.' This provision governs the territorial and hierarchical jurisdiction by ensuring that cases are filed in the lowest competent court within the relevant territorial limits to prevent overcrowding of higher courts.
2. Analysis of Option (a) Section 9: This section deals with the 'Courts to try all civil suits unless barred.' It establishes the general jurisdiction of civil courts to hear cases of a civil nature, but it does not govern the specific territorial distribution or the 'grade' of the court.
3. Analysis of Option (c) Section 10: This section deals with 'Stay of suit' (Res Sub Judice), which prevents a court from proceeding with the trial of any suit in which the matter in issue is also directly and substantially in issue in a previously instituted suit between the same parties.
4. Analysis of Option (d) Section 144: This section deals with the 'Restitution,' which allows a party to be restored to their original position if a decree is reversed or modified.
Therefore, Section 15 is the correct provision governing the placement of a suit based on the competence (grade/territory) of the court.
MCS Departmental • 2025 • Paper-III
Which one of the following is not an essential condition for applying the doctrine of res judicata under Section 11 of the CPC?
A)
Identity of subject matter
B)
Decision must be on merits
C)
Different parties in both suits
D)
Competence of earlier court
Section 11 of the Code of Civil Procedure (CPC) deals with the doctrine of Res Judicata, which prevents a court from trying a suit or issue that has already been decided by a competent court. For Res Judicata to apply, several essential conditions must be met:
1. Identity of the matter in issue: The matter in the second suit must be directly and substantially the same as in the first suit (Identity of subject matter).
2. Same parties: The parties to the suits must be the same, or parties litigating under the same title.
3. Competence of the court: The court which decided the first suit must have been competent to try the subsequent suit.
4. Decision on merits: The matter must have been heard and finally decided by the court on its merits (not dismissed on technical grounds like lack of jurisdiction or default).
Looking at the options:
- Option (a) is an essential condition.
- Option (b) is an essential condition.
- Option (d) is an essential condition.
- Option (c) 'Different parties in both suits' is the opposite of a requirement. For Res Judicata to apply, the parties must be the same or litigating under the same title. Therefore, having different parties (who are not representatives of the original parties) would generally prevent the application of Res Judicata.
MCS Departmental • 2025 • Paper-III
Under which section of the Code of Civil Procedure, 1908, can a court transfer a suit from one court to another?
A)
Section 22
B)
Section 23
C)
Section 24
D)
Section 25
The Code of Civil Procedure (CPC), 1908, provides several mechanisms for the transfer of suits.
1. **Section 24 (General power of transfer and withdrawal):** This section grants general powers to the High Court and the District Court to transfer any suit, appeal, or proceeding from one subordinate court to another, or to withdraw a case to itself. This is the primary section governing the court's power to transfer a suit.
2. **Section 22 & 23:** These sections deal with the 'Power of transfer' specifically in cases where a suit could be instituted in more than one court (concurrency of jurisdiction). Section 22 allows a defendant to request a transfer to a court where the plaintiff also has a cause of action, and Section 23 provides the rules for determining which court should handle the transfer.
3. **Section 25:** This section deals with the power of the 'Supreme Court' to transfer suits, appeals, or other proceedings from a High Court or Civil Court in one State to a High Court or Civil Court in another State in the interest of justice.
Since the question asks generally under which section a court (referring to the general administrative power of High Courts/District Courts) can transfer a suit, Section 24 is the correct answer.
MCS Departmental • 2025 • Paper-III
An ex parte decree may be set aside under Order IX Rule 13 if:
A)
The plaintiff was absent on the date of hearing
B)
The defendant shows sufficient cause for non-appearance
C)
The decree has been executed
D)
A new witness appears after decree
Under Order IX Rule 13 of the Code of Civil Procedure (CPC), if a court has passed an ex parte decree (a decree passed in the absence of the defendant), the defendant may apply to the court to set aside that decree. The court will set aside the decree if the defendant satisfies the court that: (1) the summons was not duly served, or (2) they were prevented by 'sufficient cause' from appearing when the suit was called for hearing.
Analysis of other options:
- Option (a) is incorrect because an ex parte decree is passed specifically when the defendant is absent, not the plaintiff. If the plaintiff is absent, the suit is typically dismissed under Order IX Rule 8.
- Option (c) is incorrect because the execution of a decree does not automatically grant a right to set it aside; rather, the application to set aside the decree is often filed to stop further execution proceedings.
- Option (d) is incorrect because the appearance of a new witness is a matter for appeal or review on merits, not the specific procedural ground for setting aside an ex parte decree under Order IX Rule 13, which focuses on the reason for non-appearance.
MCS Departmental • 2025 • Paper-III
Revision under Section 115 CPC lies when:
A)
The order is interlocutory
B)
The subordinate court has exercised jurisdiction illegally or with material irregularity
C)
The High Court disagrees with the findings
D)
A new fact arises after the order
Section 115 of the Code of Civil Procedure (CPC), 1908, deals with the High Court's power of Revision. Revision is a discretionary power of the High Court to ensure that subordinate courts act within the bounds of their jurisdiction.
According to Section 115, a revision application lies when a case has been decided by a subordinate court and:
1. The subordinate court has exercised a jurisdiction not vested in it by law, or
2. The subordinate court has failed to exercise a jurisdiction so vested, or
3. The subordinate court has acted in the exercise of its jurisdiction illegally or with material irregularity.
Analysis of options:
- Option (a) is incorrect because, following the 1999 and 2002 amendments to the CPC, revision is generally barred if the interlocutory order could have been challenged as an appeal or if the order is purely interlocutory in nature (Proviso to Section 115).
- Option (b) is correct as it directly mirrors the statutory language of Section 115 regarding jurisdictional errors.
- Option (c) is incorrect because Revision is not a 'second appeal'; the High Court does not revise an order simply because it disagrees with the findings of fact or law, but only when there is a jurisdictional error.
- Option (d) is incorrect because the emergence of a new fact is not a ground for Revision; Revision is based on the record of the case as it existed when the order was passed.
MCS Departmental • 2025 • Paper-III
Which of the following sections of the Code of Civil Procedure, 1908, defines the concept of “decree”?
A)
Section 2(1)
B)
Section 2(2)
C)
Section 2(9)
D)
Section 2(14)
Under the Code of Civil Procedure (CPC), 1908, the definitions of various legal terms are provided in Section 2.
1. Section 2(2) specifically defines a 'decree' as the formal expression of an adjudication which, so far as regards the Court expressing it, conclusively determines the rights of the parties with regard to all or any of the matters in controversy in the suit. It may be preliminary or final.
Analysis of other options:
- Section 2(1) is not the definition of a decree; the definitions start with 2(1) for 'decree' in some older interpretations, but in the standard 1908 Code, 2(2) is the definitive section for 'decree'.
- Section 2(9) defines 'judgment'.
- Section 2(14) defines 'rules'.
Therefore, the correct legal provision for the definition of a 'decree' is Section 2(2).
MCS Departmental • 2025 • Paper-III
Which section of the Code of Civil Procedure, 1908, deals with the power of the court to issue commissions?
A)
Section 72
B)
Section 75
C)
Section 80
D)
Section 88
Step-by-step reasoning:
1. The Code of Civil Procedure (CPC), 1908, provides for the appointment of commissions to assist the court in various tasks that cannot be efficiently performed by the court itself.
2. Section 75 of the CPC explicitly empowers the court to issue commissions for specific purposes, including: (a) examining witnesses, (b) making local investigations, (c) examining accounts, (d) making a partition, and (e) performing any other commission which may be appointed by the court.
3. Analysis of other options:
- Section 72 deals with the 'Commission to examine witnesses' specifically in the context of the court's power to examine witnesses via commission, but Section 75 is the primary substantive section granting the general power to issue commissions.
- Section 80 deals with the 'Notice' required before filing a suit against the Government or a public officer.
- Section 88 deals with the 'Execution of decree' in specific contexts (specifically relating to the transfer of decrees).
Therefore, Section 75 is the correct and authoritative section dealing with the power of the court to issue commissions.
MCS Departmental • 2025 • Paper-III
Which of the following is not a condition for applying the doctrine of res judicata under Section 11?
A)
Same parties or their representatives
B)
Competent jurisdiction of the earlier court
C)
Matter must have been decided on merits
D)
The former decision must be appealable
Section 11 of the Code of Civil Procedure (CPC) embodies the doctrine of Res Judicata, which prevents the same parties from litigating the same issue once it has been decided by a competent court. For Res Judicata to apply, the following conditions must be met:
1. The matter must be directly and substantially in issue in both the former and the subsequent suit.
2. The parties must be the same or litigating under the same title (Option a).
3. The court that decided the former suit must have been a court competent to try the subsequent suit (Option b).
4. The matter must have been heard and finally decided on its merits (Option c).
Option (d) is NOT a condition because the doctrine of res judicata applies regardless of whether the decision was appealable or whether an appeal was actually filed. Once a competent court delivers a final judgment on the merits, it is binding between the parties, whether or not the law provided a right to appeal that specific decision.
