In Irish law, provocation is a partial defence applicable only to murder. When raised successfully, it operates to reduce murder to the lesser charge of manslaughter. The basis for this is that the accused lost self-control in response to provocation. The test for the defence of provocation, set out by the Court of Criminal Appeal in the case of The People (DPP) v. MacEoin, is a predominantly subjective test.
The Law Reform Commission considered the defence of provocation in its 2009 Report on Defences in Criminal Law. The Commission recommended that provocation should be retained as a partial defence to murder. However, the Commission also concluded that the defence of provocation should be modified and reformed. In particular, the Commission recommended a withdrawal from a purely subjective test and the introduction of a defence remodelled on objective lines.
The recommendations of the Law Reform Commission regarding the defence of provocation are under consideration within my Department.
