Q: What are the legal guidelines regarding access to high school premises after hours in California?

A: Under California law, your rights as an alumnus visiting your former high school campus are governed by several key provisions. The situation you described raises important legal considerations about public access to school grounds.

California Penal Code Section 626.8 establishes that persons without "lawful business" on school grounds whose presence interferes with school activities may be asked to leave by school officials. The code defines "lawful business" as "a reason for being present upon school property which is not otherwise prohibited by statute, by ordinance, or by any regulation adopted pursuant to statute or ordinance." Watching a sporting event would typically constitute lawful business, but schools maintain authority to establish reasonable conditions.

Individual school districts generally set their own policies regarding visitor access to campus facilities after regular school hours. These policies vary between districts, with some allowing open access to playing fields and grounds while restricting access to school buildings. The track coach's instructions about where you could stand and park appear to be an exercise of this administrative authority, which schools possess to maintain order and safety.

When visiting school sporting events, you are subject to both state law and local school policies. Many districts have specific regulations about spectator conduct and designated viewing areas, including rules that spectators must be "kept completely away from the field before, during and after" sporting events. Schools can enforce these policies even when no explicit signs are posted, though posting requirements may vary by district.

If you wish to attend future events, you might consider contacting the school administration directly to inquire about visitor policies for alumni. While schools have broad authority to manage their grounds, they generally welcome community and alumni participation in appropriate settings when proper protocols are followed.
