Recall of MPs Bill

I think that this is a misunderstanding. The leader of the party has to sign to allow them to use the party logo in an election, and they may not be permitted to stand for a political party, but that does not prevent them standing in a by-election. I suspect that if Jimmy Maxton had run in that election, he might well have received the signature of the leader of the Labour Party, but in other circumstances it might have been withheld. It does not prevent someone running again in the election; they are not denied this chance; and the electorate are not denied the opportunity to support them. It just means that they will not be allowed under their party act to run as a party candidate.
