In jurisprudence, double jeopardy is a procedural defence that prevents an accused person from being tried again on the same charges following an acquittal or conviction and in rare cases prosecutorial and/or judge misconduct in the same jurisdiction. Double jeopardy is a common concept in criminal law. In civil law, a similar concept is that of res judicata. Variation in common law countries is the peremptory plea, which may take the specific forms of autrefois acquit or autrefois convict. These doctrines appear to have originated in ancient Roman law, in the broader principle non bis in idem.
Perjury is the intentional act of swearing a false oath or falsifying an affirmation to tell the truth, whether spoken or in writing, concerning matters material to an official proceeding.

In English law, provocation was a mitigatory defence to murder which had taken many guises over generations many of which had been strongly disapproved and modified. In closing decades, in widely upheld form, it amounted to proving a reasonable total loss of control as a response to another's objectively provocative conduct sufficient to convert what would otherwise have been murder into manslaughter. It only applied to murder. It was abolished on 4 October 2010 by section 56(1) of the Coroners and Justice Act 2009, but thereby replaced by the superseding—and more precisely worded—loss of control.

R v Davis [2008] UKHL 36 is a decision of the United Kingdom House of Lords which considered the permissibility of allowing witnesses to give evidence anonymously.

United States v. Valenzuela-Bernal, 458 U.S. 858 (1982), is a United States Supreme Court case that determined the constitutionality of deporting aliens who might give testimony in criminal alien smuggling prosecutions. Because deporting alien witnesses might take away a testimony that would be both “material and favorable” to the defendant, it gives rise to a potential motion from the defense to dismiss the indictment under the Compulsory Process Clause of the Sixth Amendment and the Due Process Clause of the Fifth Amendment.
