Short answers, pulled from the story.
The Code of Ur-Nammu was enacted by King Ur-Nammu of Ur between 2100 and 2050 BC. This ancient Sumerian document represents the earliest known attempt to codify criminal behavior and predates the Code of Hammurabi by centuries. It established a system of monetary compensation for injuries rather than physical punishment.
The theologian Alfonso de Castro introduced the radical idea that God's eternal penalty should be transferred from the spiritual realm to secular courts during the 16th century. This theological debate in Spanish Late Scholasticism created the foundations of Early Modern criminal law. German jurist Benedikt Carpzov and Italian statesman Giulio Claro later codified these ideas.
The 1966 case of R v. Church established the principle that the mental state and the physical act must align in time or in a causal chain to constitute a crime. The court ruled the defendant was guilty of manslaughter but not murder because his intent to kill did not coincide with the act that caused the death. This ruling solidified the requirement for the simultaneous presence of actus reus and mens rea.
The thin skull rule was solidified in the 1975 case of R v. Blaue and holds that a criminal is responsible for the full extent of the harm they cause even if the victim has a unique vulnerability. The court ruled the defendant must take his victim as he finds them, meaning the killer was responsible for the death despite the victim's refusal of life-saving treatment. This principle ensures offenders are accountable for consequences that are far worse than expected.
Criminal law operates under five competing objectives: retribution, deterrence, incapacitation, rehabilitation, and restoration. Retribution balances the scales of justice, deterrence discourages reoffending, and incapacitation removes dangerous individuals from the community. Rehabilitation focuses on reintegration while restoration seeks to repair the injury inflicted upon the victim.
The International Criminal Court was established in 1998 through the Rome Statute to prosecute genocide, crimes against humanity, and war crimes. This permanent body emerged from the precedent set by the Nuremberg trials which held individuals criminally liable for violations of international law. The court allows for the prosecution of crimes regardless of where they were committed or the nationality of the perpetrator.
