The new Rules of the CERN Health Insurance Scheme (CHIS) came into force on 1 January 2023.
The change concerns the addition of Article I. 1.07:
"I. 1.07 GUARANTEE OF BENEFITS
CERN guarantees the benefits acquired under the CHIS Rules by the Scheme’s Members until the cessation of the rights of the last Member.
In the event of the Organization’s dissolution, the CERN Council will take the measures needed to guarantee the rights acquired on the date of dissolution."
