Germany did the first step for SSM. The Bundestag has voted in favor for it.
The second step is a given, the Bundesrat will accept this bill on the 07.07. It was introduces by them in the first place.

Then someone (Bayern definitely) will put it in front of the Supreme Court. While it is not sure how the Supreme Court would decide now, the decision will take years, which means thousands of people already married. And it is harder to take rights away than to give them.
