ex p. stands for Ex parte (on the application of), a Latin legal abbreviation.

Prefix in older English and Commonwealth case names identifying the party who applied for a prerogative remedy such as judicial review, as in "R v Secretary of State for the Home Department, ex p Doody". Modern cases use "R (on the application of X)" instead.

Example: In R v Secretary of State for the Home Department, ex p Doody, the Lords required reasons for tariff decisions.

Usage notes

The naming format changed when new judicial review rules took effect in October 2000. In US usage, "ex parte" usually describes a proceeding or communication involving only one side, such as an ex parte application for a TRO, and is written in full, as in the case name Ex parte Milligan (1866).
