SAN FRANCISCO -- In the days leading up to the California Supreme Court's historic same-sex marriage ruling Thursday, the decision "weighed most heavily" on Chief Justice Ronald M. George -- more so, he said, than any previous case in his nearly 17 years on the court.

But as he read the legal arguments, the 68-year-old moderate Republican was drawn by memory to a long ago trip he made with his European immigrant parents through the American South. There, the signs warning "No Negro" or "No colored" left "quite an indelible impression on me," he recalled in a wide-ranging interview Friday.

"I think," he concluded, "there are times when doing the right thing means not playing it safe."

Asked whether he thought most Californians would accept the marriage ruling, George said flatly: "I really don't know."
