The government lost 14 votes in the House of Lords on the detail of the Police, Crime Sentencing and Courts Bill on Monday 18th January 2022, to add to the five previous defeats in earlier debates.
Most of these are reversible in the Commons because they represent changes to the bill, but the government was also trying to add in some changes of its own, introducing a series of new public order offences aimed at preventing a recurrence of last year's Insulate Britain and Extinction Rebellion protests. Because the Lords blocked these from becoming part of the bill, they won't be sent back to the Commons.
Labour had approached this issue warily, conscious that they could be accused of allowing the rights of protesters to trump the rights of ordinary people to go about their lives, so they proposed what they regarded as a more focused alternative - but ended up helping vote down the government's new clauses as unacceptable on civil liberties grounds.
My best guess is that the government's proposals will resurface as a free standing public order bill, when the new Parliamentary year begins in April.
Other amendments on subjects like misogyny, noise at demonstrations, drink-spiking, the Police duty of candour, the repeal of the Vagrancy Act and many more, will have to be agreed by MPs.
This is what's known as "Parliamentary ping pong", in which a bill bounces between the Commons and the Lords until both have agreed on its final form, and it can run on for quite a while.
It will have to be completed before the end of the current parliamentary session, expected in late March or April. 2022
