A Los Angeles judge has denied a request from an AIDS advocacy group calling for mandatory use of condoms on porn sets.

Judge David Yaffe on Tuesday rejected a petition from the AIDS Healthcare Foundation that contended county health officials hadn't done enough to prevent sexually transmitted diseases in the porn industry.

The group sued the county in July after data showed there were more than 3,700 STD cases over the past five years reported by a clinic that serves porn actors.

In denying the foundation's request, Yaffe said the county has broad discretion in how it oversees public health. The group plans to appeal the decision.
