John McDonnell MP’s Private Member’s Bill, which would have stopped courts ruling out strike ballots on small technicalities, was defeated in Parliament on 22 October.
Ed Miliband, when standing for Labour leader, volunteered to back moves to stop judges invalidating strike ballots on the basis of minor errors.
But Labour’s front bench refused to back McDonnell’s Bill, and would not mobilise enough Labour MPs to get the Bill on to its next stage.
A total of 89 Labour MPs turned up to support the Bill, including two who acted as tellers in a procedural vote of 87 to 27. But the Bill fell into a parliamentary black hole because at least 100 supporters were required to force a vote on the second reading.
