It hasn’t yet attracted headlines or much discussion over here, but last week a federal judge in California overturned a piece of legislation called Proposition 8 which defended marriage as between a man and a woman. Apparently a same-sex couple had challenged this ruling as "unconstitutional" and Judge Vaughn Walker proceeded to strike it down, even though a huge number of Californians – seven million at the last count - had voted for it. There is to be an appeal and the question is likely to end up in the Supreme Court. If the Supreme Court were to uphold Judge Vaughn Walker the reverberations for the whole of American society would be grave indeed.
