• (law, now historical) The offence in English law of bringing suit in or obeying a foreign (especially papal) court or authority, thus challenging the supremacy of the Crown. The offence was created by the Statute of Praemunire 1393 (16 Richard II, chapter 5), and abolished by the Criminal Law Act 1967 (chapter 58).
  "Lord Cardinall, the Kings further pleaſure is, / Becauſe all thoſe things you haue done of late / By your power Legatiue within this Kingdome, / Fall into' th' compaſſe of a Premunire; / That therefore ſuch a Writ be ſued againſt you, / To forfeit all your Goods, Lands, Tenements, / Caſtles, and whatſoever, and to be / Out of the Kings protection. This is my Charge."
• (in extended use) Any of a number of criminal offences incurring similar penalties to the original offence of praemunire.
  "[T]he term ‘Præmunire’ […] has subsequently, to use the language of Mr. Serjeant Hawkins (Pleas of the Crown, b. 1, c. 19), ‘been applied to other heinous crimes, for the most part having relation to the offences originally coming under the notion of præmunire, but in some instances not at all.’ The Habeas Corpus Act (31 Car. II c. 12) [sic: the Habeas Corpus Act 1679 (31 Car. II, chapter 2)] contains an instance of the latter mode of application. By the 12th [sic: 11th] section of that act it is made a Præmunire to send any inhabitant of England, Wales, or the town of Berwick-upon-Tweed, a prisoner beyond the seas in defiance of its provisions to the contrary."
• (figurative) Crime, offence, wrongdoing.

• (figurative) A difficulty or predicament.
  "This attendance increased his uneasiness to such a degree, that he […] swore, that if once he was clear of this scrape, he would not bring himself into such a premunire again for the whole kingdom of France."
