The Parliament of Eswatini is bicameral, consisting of a lower chamber and an upper one. Some of the members of both chambers are elected, while the rest are appointed by the King of Eswatini. Election is by secret ballot in a first-past-the-post system of voting. Members of both chambers serve for five-year terms. All candidates run on a non-partisan basis, as political parties are banned.

The Appeal Court declared the act unconstitutional, and on 12 April 1973 the parliament passed a motion that "called on the king to devise ways and means of dealing with the crisis". The result was that King Sobhuza suspended the constitution, dismissed Parliament, banned all political parties and became an absolute monarch.
