An interim report was published on 28 March 1922, the first official report of the new Parliament of Northern Ireland, and it was subsequently accepted by the Northern Ireland Government. On 29 April 1922, King George V granted to the force the name Royal Ulster Constabulary (RUC). In May, the Parliament of Northern Ireland passed the Constabulary Act 1922 and the RUC officially came into existence on 1 June. The headquarters of the force was established at Atlantic Buildings, Waring Street, in Belfast. The uniform remained essentially the same as that of the RIC – a dark green, as opposed to the dark blue worn by the other British police forces and the Garda Síochána. A new badge of the Red Hand of Ulster on a St George's Cross surrounded by a chain was designed but proved unpopular and was never uniformly adopted. Eventually the harp and crown insignia of the Order of St Patrick, as worn by the RIC, was adopted.
