Sample JNJ Concurso de Jueces y Fiscales Practice Questions

Try these sample questions to review concepts for the JNJ Concurso de Jueces y Fiscales exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 90+ question experience with AI tutoring.

1Under article VII of the Preliminary Title of the Nuevo Código Procesal Constitucional, when does a Tribunal Constitucional judgment become binding precedent?
A.Automatically, for every judgment that ends a constitutional process
B.Whenever three consecutive judgments resolve similar cases the same way
C.When the judgment expressly says so and defines the scope of its effect
D.Only once Congress ratifies the rule laid down by the judgment
Explanation: Article VII provides that firm TC judgments constitute binding precedent when the judgment so states, specifying the normative scope of its effect. When the Tribunal departs from a precedent, it must state the factual and legal grounds supporting the change.
2Under article 2.24.f of the Constitution, within what general period must a detainee be placed at the disposal of the competent court?
A.Within 24 hours, with no exception at all
B.Within 48 hours, or the term of distance
C.Within 72 hours in every type of case
D.Within 7 days, if the police request it
Explanation: Article 2.24.f allows detention only by a written, reasoned judicial order or by the police in flagrante delicto, and requires the detainee to be placed at the court's disposal within forty-eight hours or the term of distance. Longer periods apply only to the specific offenses the article lists.
3In the Tribunal Constitucional's classification of hábeas corpus, which type is used to stop unlawful worsening of the conditions of a lawful detention?
A.Hábeas corpus instructivo
B.Hábeas corpus preventivo
C.Hábeas corpus traslativo
D.Hábeas corpus correctivo
Explanation: The TC (Exp. 2663-2003-HC/TC) described hábeas corpus correctivo as the remedy against acts that unlawfully or arbitrarily worsen the form and conditions in which a detention is served. The preventive type addresses imminent threats, the traslativo addresses undue prolongation, and the instructivo seeks to locate a disappeared person.
4What is an 'additive' (aditiva) judgment of the Tribunal Constitucional?
A.It strikes the entire statute out of the legal order at once
B.It finds a provision unconstitutional for an omission and extends it
C.It refuses to review the statute because the plaintiff lacked standing
D.It urges Congress to legislate, without changing the law's content
Explanation: Manipulative judgments include reductive, additive and substitutive types. An additive judgment declares a provision unconstitutional for failing to include something required by the Constitution and extends its content to the omitted case. A purely exhortative judgment only urges the legislator to act.
5Under article 103 of the Constitution, when may a law apply retroactively?
A.Never, under any circumstances
B.In tax matters, when it increases revenue
C.In labor matters, whenever Congress so decides
D.In criminal matters, when it favours the accused
Explanation: Article 103 states that no law has retroactive force or effect, except in criminal matters when it favours the accused. Laws apply from their entry into force to the consequences of existing legal relations and situations.
6In Barrios Altos v. Peru (2001), what did the Inter-American Court decide about Peru's amnesty laws (Leyes 26479 and 26492)?
A.They were valid, but Peru had to compensate the victims for them
B.They were valid because the Peruvian Congress had approved them
C.They were incompatible with the Convention and lacked legal effect
D.They fell outside the Inter-American Court's jurisdiction
Explanation: In Barrios Altos the Inter-American Court held that self-amnesty laws preventing investigation and punishment of serious human-rights violations are incompatible with the American Convention and lack legal effect, so they cannot obstruct investigation of the facts.
7Under article 46 of the American Convention on Human Rights, which requirement generally applies to an individual petition before the Inter-American Commission?
A.A prior advisory opinion issued by the Inter-American Court
B.Approval of the petition by the Peruvian Congress beforehand
C.Payment of a filing fee to the Inter-American Commission
D.Exhaustion of domestic remedies and filing within six months
Explanation: Article 46 requires, as a rule, that domestic remedies have been pursued and exhausted, that the petition be lodged within six months of notification of the final decision, and that the matter is not pending in another international proceeding. Exceptions apply when domestic remedies are unavailable or ineffective.
8Under article 61 of the American Convention, who may submit a contentious case to the Inter-American Court?
A.Any person directly, without going through the Commission
B.Only the States Parties and the Inter-American Commission
C.Only non-governmental organizations
D.Only the Organization of American States General Assembly
Explanation: Article 61 states that only the States Parties and the Commission have the right to submit a case to the Court. Victims take part in the proceedings once the case is before the Court, but individuals cannot bring cases directly.
9Under article 27 of the American Convention, which right may NOT be suspended even in a state of emergency?
A.Freedom of peaceful assembly
B.Freedom of movement and of residence in the territory
C.The right to humane treatment (integrity)
D.The inviolability of the home
Explanation: Article 27.2 lists rights that cannot be suspended, including juridical personality, life, humane treatment, freedom from slavery, freedom from ex post facto laws, freedom of conscience and religion, rights of the family and the child, name, nationality, political rights, and the judicial guarantees essential to protect them.
10Which principle of international human rights law requires choosing the norm or interpretation most protective of the person?
A.Principle of reciprocity between States
B.Lex posterior principle
C.Principle of state sovereignty
D.Pro persona (pro homine) principle
Explanation: The pro persona principle requires applying the broadest norm or interpretation when recognizing protected rights and the most restrictive one when establishing limits on them. Human-rights treaties are not governed by reciprocity.
