I think there’s scope for a Position Statement here, or at least a press release.
To be released at conclusion of the high court challenges.
If the HC lets it go ahead:
“This is a civil rights issue. While our position goes further, the proposed changes get us closer to equality. We’re not going to pass up an incremental improvement once it’s here (even if the mechanism is daft). Vote Yes.”
If the HC cans it:
“This is a civil rights issue, it shouldn’t even need to be voted on in this way, we’re glad the HC canned it. While our position goes further, there’s no reason Parliament can’t make incremental improvements now.”
