The powers of the President can be considered more ceremonial than real. Critically discuss this statement taking into account relevant constitutional provisions and decided case law.
A presidential system is a democratic and republican government in which a head of government leads an executive branch that is separate from the legislative branch. This head of government is in most cases also the head of state, which is called president.
In presidential countries, the executive is elected and is not responsible to the legislature, which cannot in normal circumstances dismiss it. Such dismissal is possible, however, in uncommon cases, often through impeachment.
The title “president” has persisted from a time when such person personally presided over the governing body, as with the President of the Continental Congress in the early United States, prior to the executive function being split into a separate branch of government.
A presidential system contrasts with a parliamentary system, where the head of government comes to power by gaining the confidence of an elected legislature. There are also hybrid systems such as semi-presidentialism.
