There are unconfirmed rumors that Harav Suriel Rsoenberg has backed out of the Beis Din due to being fed-up with the Halpern's dictating what and when the B'D' should be set-up and also because of tremendous pressure from the Golderes Green Rabonim not to challenge their decision.
Harav Suriel was the original and first Dayan on the Beis Din, as such he was the backbone of the entire panel.
Also one of the Dayanim, Rav Naftuli Nuesbaum, explicitly said he will not come to London, the Union is still actively looking for a replacement.
Well, not necessarily a replacement, because on the Psak it will still be under his name, but something like a Vice Dayan on behalf of him.
One of the Dayanim that were in talks about coming in his place, recently gave the 'no' answer, so we're back to square one, looking for a Beis Din..
If all true, something major will follow shortly, as either the Union throws out BMDC, or that RPR and RYMG etc, leave the union.
