If Theresa May's proposals get put to the EU, and accepted, I can now see a benefit to Gina Miller's court case. Only now it could be the Brexit supporters who decide to vote against implementation on the current terms.

The Millar case was never about Brexit as such, it was about the relationship between the authority of government and Parliament. So it matters not a jot to me who sees that being to their benefit: getting the relationship right is what is important.
