style used is normally His Excellency/Her Excellency (); sometimes people may orally address the president as 'Your Excellency' ( ), or simply 'President' ( (vocative case)). The Presidential Salute is taken from the National Anthem, "Amhrán na bhFiann". It consists of the first four bars followed by the last five, without lyrics. Inauguration The inauguration ceremony takes place on the day following the expiry of the term of office of the preceding president. No location is specified in the constitution, but all inaugurations have taken place in Saint Patrick's Hall in the State Apartments in Dublin Castle. The ceremony is transmitted live by national broadcaster RTÉ on its principal television and radio channels, typically from around 11 am. To highlight the significance of the event, all key figures in the executive (the government of Ireland), the legislature (Oireachtas) and the judiciary attend, as do members of the diplomatic corps and other invited guests. During the period of the Irish Free State (1922 to 1937), the governor-general had been installed into office as the representative of the Crown in a low-key ceremony, twice in Leinster House (the seat of the Oireachtas), but in the case of the last governor-general, Domhnall Ua Buachalla, in his brother's drawing room. By contrast, the Constitution of Ireland adopted in 1937 requires the president's oath of office be taken in public. Impeachment and removal from office The president can be removed from office in two ways, neither of which has ever been invoked. The Supreme Court, in a sitting of at least five judges, may find the president "permanently incapacitated", while the Oireachtas may remove the president for "stated misbehaviour". Either house of the Oireachtas may instigate the latter process by passing an impeachment resolution, provided at least thirty members move it and at least two-thirds support it. The other house will then either investigate the stated charges or commission a body to do so; following which at least two-thirds of members must agree both that the president is guilty and that the charges warrant removal. Security and transport As head of state of Ireland, the president receives the highest level of protection in the state. Áras an Uachtaráin is protected by armed guards from the Garda Síochána and Defence Forces at all times, and is encircled by security fencing and intrusion detection systems. At all times the president travels with an armed security detail in
