The Supreme Court on Monday agreed to referee a dispute between NASA and some of its independent contractors over required security checks, a decision that could affect how the federal government investigates the background of current and future employees.

The justices agreed to hear an appeal from the space agency, which had its worker investigations at Jet Propulsion Laboratory in California blocked after the 9th U.S. Circuit Court of Appeals said the questions threatened the constitutional rights of workers.

The high court's decision in this case could throw into question the background checks routinely done on all federal government workers.

While the case before the court deals solely with whether to dissolve the temporary restraining order placed on NASA's background checks at the Jet Propulsion Laboratory, NASA said in its filings that the forms in question "are the same ones that have long been used to conduct background checks for applicants for federal employment."

Twenty-eight scientists and engineers from the Jet Propulsion Laboratory sued the federal government after NASA required them to submit to background checks. They said the agency was invading their privacy by requiring the investigations, which included probes into medical records and questioning of friends about everything from their finances to their sex lives.
