HB 523 introduces changes to limit the authority of the Texas government during declared states of disaster, requiring disaster orders to be narrowly tailored, temporary, and justified by compelling public health or safety needs. The bill emphasizes protecting constitutional rights during emergencies and grants state courts the power to review and invalidate orders that do not meet these criteria. Only the governor may issue orders significantly infringing on constitutional rights, such as freedoms of movement, speech, and religious exercise, with such orders expiring after 30 days unless extended by the legislature. The bill also permits remote legislative voting during emergencies and prevents the governor from reissuing similar orders without substantial justification. Additionally, it restricts the suspension of statutes during disasters, limiting suspensions to state agency rules under specific circumstances.
