No joy in lesbian housing case...

I just finishing covering one of those court cases that leaves you feeling baffled and slightly lost for words.
A lesbian couple wants joint tenancy of a government flat but are told they can’t have it. Government policy is that unmarried couples can’t have joint tenancy (unless there’s a chid involved).
So what’s the problem? Just get married. It’s a good solution for the heterosexuals, not so good if you’re homosexual though. Gay marriage? Not allowed, I’m afraid.
The lesbian couple challenge the decision on the grounds of discrimination, human rights etc and lose - twice! (Read about the first time here)
Here’s what I don’t get: this couple has been in a monogamous, loving relationship for nearly 20 years. On what possible grounds could anyone say no to giving them a government lease that is in both their names and therefore protects both their futures? On the grounds of protecting the ‘traditional family’ unit? Would that be the traditional, divorce-prone family unit?
I can’t understand the government’s approach to this issue. It seems outdated and out of touch with modern reality. At least, for me it does.
But watch this space. Methinks this case could go all the way Europe. This argument may not be over yet.
