DETROIT — A judge barred an Ivy League law student Monday from testifying at Michigan’s gay marriage trial, saying he might become an expert witness someday but his opinions wouldn’t help sway this case.
It was a blow for the Michigan attorney general’s office, which had offered Sherif Girgis as its first witness in defense of a 2004 constitutional amendment that bars same-sex marriage.
Girgis has written and talked about a historical defense of marriage between a man and a woman going back to ancient philosophers such as Cicero and Plato. He’s pursuing a law degree at Yale University and a doctorate in philosophy in Princeton University.
“The fact is you’re still a student. Someone else is still grading your papers,” said attorney Ken Mogill, co-counsel for two Detroit-area nurses challenging the gay-marriage ban.
