WASHINGTON  Unusual practices in Georgia trial courts, including off-color gifts to court personnel from jurors in a capital case, were the subjects of a pair of unsigned Supreme Court decisions on Tuesday.

The court also declined to intercede for now in two closely watched cases, one involving Asian carp threatening to invade Lake Michigan, the other a lower court decision ordering California to release more than 40,000 prison inmates.

In one of the Georgia cases, Presley v. Georgia, No. 09-5270, the Supreme Court decided two open issues concerning closed courtrooms. The trial judge had ejected an uncle of the defendant during jury selection, saying her courtroom was too small to accommodate both potential jurors and the public.

The defendant, Eric Presley, was convicted of trafficking in cocaine. He appealed, saying his Sixth Amendment right to a public trial had been violated. In 1984, the Supreme Court ruled that the press and the public have a First Amendment right of access to jury selection; in Mr. Presley’s case, the court Tuesday extended that right to criminal defendants under the Sixth Amendment.
