An excerpt from the article 45 facts about Switzerland

The position of the parliament and cantonal authorities is particularly strong there - such a system is called a parliamentary committee, and its most typical feature is the lack of separation between the legislative, executive, and judicial powers.

Switzerland is a federation divided into 26 cantons that are state entities. The division of competencies between the federation and the cantons is determined by the constitution.

There is no constitutional court in Switzerland.
