On June 30, the Supreme Court issued a profound victory for the press. It ruled 6-3 in favor of the newspapers, establishing the principle that the government can almost never exercise “prior restraint”—preventing the publication of sensitive or embarrassing material before it sees the light of day.
“Only a free and unrestrained press can effectively expose deception in government,” Justice Hugo Black wrote in his opinion supporting the decision.
But although the Court established that under most circumstances the government can’t stop the publication of truthful information on matters of public concern, there are exceptions.
“Never doesn’t really mean never,” says Freeman of the Media Law Resource Center. The government can prevent publication if it would pose a grave danger to national security—for example, a newspaper lays out battle plans, permitting an enemy to directly endanger the lives of American soldiers. The ruling in the Pentagon Papers case also didn’t bar the federal government from pressing criminal charges after publication or prosecuting leakers.
As for Ellsberg, he had been charged with conspiracy, espionage, and theft of government property. But the charges were thrown out when it was disclosed that a secret White House investigation unit working for Nixon’s administration had broken into the office of Ellsberg’s therapist, seeking derogatory information to discredit him. Some of those same people later broke into the Democratic Party headquarters at the Watergate Office Building, setting off what became known as the Watergate scandal that led to Nixon’s resignation.
