Establishes immunity from civil liability for certain actions taken by private schools related to access to restrooms or changing areas

HB 1197 protects private K-12 schools from civil lawsuits when they establish single-sex restrooms or changing areas based on students' sex as defined by their original birth certificate. The bill defines "sex" as male or female based on genetics/physiology at birth and specifies that schools cannot be liable for designating restrooms exclusively for males or females to ensure privacy and safety. It also prohibits local governments from banning such policies and requires them to cover schools' legal costs if they challenge the policy. This law directly affects private schools and their restroom access policies, with no provisions for emergency medical or maintenance access.
