The Lord Lieutenant of Scotland is the title of the viceroy of Scotland. The Lord Lieutenant exercises all the powers of the monarch within Scotland. The powers of the Lord Lieutenant can be overruled by the Sovereign, though this has never occurred. The Lord Lieutenant's power is superceded by that of the Sovereign. This means that when the Sovereign is in Scotland, the Lord Lieutenant's power is transferred by default to the Crown. The office of Lord Lieutenant predates the current system by centuries. The first modern Lord Lieutenant was appointed by virtue of the Devolution Act of 1937, which re-organised the structure of the British government to appease dissent within Scotland and Wales due to the Home Rule agreement in Ireland. The Lord Lieutenant resides in the Palace of Holyrood
