The Language of the Law
Mens rea, tort, hearsay and the other terms that do the heavy lifting in a courtroom.
In criminal law, what does mens rea refer to?
Ten questions on legal principles and institutions, each with the Latin translated and the mechanism explained.
Legal vocabulary leaks into everyday speech and loses precision on the way. This quiz restores it: what the presumption of innocence requires in practice, what a jury decides and what it does not, and where the great charters and conventions actually apply. It covers both national structures and the international courts that sit above them. The explanations translate the Latin and describe how each principle works, without being advice or tied to a single country\'s system unless the question says so.
Every question in this quiz is listed below with its correct answer and the reasoning behind it. Play first if you would rather not see the answers — or read through as a study sheet.
Play it insteadAnswer: D. The presumption of innocence
Why: It places the burden of proof on the prosecution rather than the accused. It does not mean a court believes the defendant, only that it must be convinced.
Answer: C. 1215
Why: It was agreed between King John and rebel barons at Runnymede. Most of its clauses have been repealed, but the principle of limits on royal power endured.
Answer: C. Unlawful detention
Why: It requires that a detained person be brought before a court to test the legality of their detention. The Latin means roughly "you shall have the body".
Answer: D. The Hague
Why: It is the principal judicial organ of the United Nations, based in the Peace Palace. The separate International Criminal Court is also in The Hague.
Answer: C. Precedent set by earlier decisions
Why: Judges are bound by relevant earlier rulings, so law develops case by case. Civil law systems instead work primarily from comprehensive written codes.
Answer: C. Questions of fact
Why: Juries determine what happened, while the judge rules on law and usually decides sentence. The division is a defining feature of the system.
Answer: D. The conduct of armed conflict
Why: They set protections for wounded soldiers, prisoners of war and civilians. Nearly every state in the world is a party to them.
Answer: B. Elsewhere
Why: An alibi is evidence that the accused was somewhere else when the offence occurred. The everyday sense of a general excuse came later.
Answer: B. England and Wales
Why: Solicitors traditionally advise clients and prepare cases, while barristers argue in the higher courts. Many jurisdictions merge the two roles entirely.
Answer: D. The legislature
Why: Legislatures debate and pass statutes, while courts interpret them and the executive applies them. Heads of state often hold a formal power of assent.
