The PSNI was initially legally obliged to operate an affirmative action policy of recruiting 50% of its trainee officers from a Catholic background and 50% from a non-Catholic background, as recommended by the Patten Report, in order to address the under-representation of Catholics that had existed for many decades in policing; in 2001 the RUC was almost 92% Protestant. Many unionist politicians said the "50:50" policy was unfair, and when the Bill to set up the PSNI was going through Parliament, Minister of State Adam Ingram stated: "Dominic Grieve referred to positive discrimination and we hold our hands up. Clause 43 refers to discrimination and appointments and there is no point in saying that that is anything other than positive discrimination." However, the Northern Ireland Human Rights Commission cited international human rights law to show that special measures to secure minority participation were in accordance with human rights standards and did not in law constitute 'discrimination'.
