Parliamentary systems in the context of "President of Portugal"

Primary legislation and secondary legislation (the latter also called delegated legislation or subordinate legislation) are two forms of law, created respectively by the legislative and executive branches of governments in representative democracies. Primary legislation generally consists of statutes, also known as "acts", that set out broad principles and rules, but may delegate specific authority to an executive branch to make more specific laws under the aegis of the principal act. The executive branch can then issue secondary legislation (often by order-in-council in parliamentary systems, or by regulatory agencies in presidential systems), creating legally enforceable regulations and the procedures for implementing them.

In the politics of the United States, a government trifecta is a political situation in which the same political party controls the presidency and both chambers of Congress. The term is primarily used in the United States, where it originated, but can be used for control of the executive branch and both chambers of the legislative branch in any country that has a bicameral legislature and an executive that is not fused. It is borrowed from horse race betting.

Most countries and all democracies have some degree of separation of powers into separate branches of government, typically consisting of an executive, a legislative, and a judicial branch, but the term government trifecta is primarily applied to countries in which the executive is not elected by the legislature and where the legislature is not sovereign; in parliamentary systems, the executive or part of it is elected by the legislature and must have the support of the majority of Parliament.
