Chief Justice Roberts was hospitalized overnight after head injury in June

WASHINGTON — Chief Justice John Roberts was hospitalized overnight last month for an injury he suffered to his forehead after falling while walking for exercise, a U.S. Supreme Court spokeswoman said.

Roberts’ doctors believe the fall was because of lightheadedness caused by dehydration and have ruled out a seizure, spokeswoman Kathy Arberg said. Roberts, 65, has suffered from at least two seizures in the past.

“The injury required sutures, and out of an abundance of caution, he stayed in the hospital overnight and was discharged the next morning,” Arberg said in an email.

The Washington Post was the first to report that Roberts had been hospitalized. The newspaper said it received a tip that the court then confirmed. The Post said the incident happened at the Chevy Chase Club in Maryland, where Roberts and Justice Brett Kavanaugh are members.

Supreme Court justices make their own individual decisions about what medical information to release to the public, and some are more forthcoming than others.

The revelation comes as the Supreme Court prepares to issue the final opinions of its 2019-20 term, starting Wednesday.

The court will be ruling on congressional and New York grand jury subpoenas for President Donald Trump’s financial records and on Trump’s effort to carve out a broad religious exemption from the Affordable Care Act requirement that employers and universities offer free contraceptives on their health care plans.
