The Supreme Court left intact Tuesday a ruling that says public schools that allow civic groups and others to rent school space cannot refuse such access to religious organizations.

The justices, without comment, turned down the appeal of a Pennsylvania high school forced to rent weekend use of its auditorium to the Campus Crusade for Christ.The top court in June upheld the federal Equal Access Act, in which Congress required that virtually all public high schools must allow student prayer groups to meet and worship if other student clubs are permitted at school.

In other action Tuesday, the Supreme Court:

- Agreed to decide whether police may conduct random drug searches aboard buses and trains after passengers have consented.

The court said it would review a Florida court ruling that the searches violate passengers' rights.

- Refused a request to review the constitutionality of the Army's urinalysis drug testing program.

At issue was whether a urinalysis test performed without suspicion and conducted as part of a military commander's inspection of his troops violated the Fourth Amendment's protection against unreasonable searches and seizures.

- Let stand a ruling that a Texas child's constitutional rights were not violated when he allegedly was beaten by his school principal.

Ronald and Nancy Fee said school principal Joseph Herndon brutally beat their son, Tracy, 12, when he refused to submit to being paddled three times for misbehaving in class.

The Fees said Herndon punched Tracy on the jaw and held him down on the floor and hit him numerous times on the buttocks with a paddle.

Herndon and a teacher said the principal paddled the boy three times but did no more.

- Turned away a multibillion dollar dispute over natural-gas costs.

The court, without comment, refused to reinstate a federal regulation to ease a burden on pipeline companies.
