After 10 years as an Observer, Switzerland has now become a full Member of ICOS. The membership required a particular decision by the Swiss parliament to allow membership in an EU organisation such as ICOS. Only five other ERICs were given the same status. The Swiss application was accepted at the ICOS General Assembly in May 2023. With full membership, ICOS Switzerland will get voting rights in the General Assembly, the highest decision-making body of ICOS.
