Protesters took to the streets across Wales as part of a UK-wide opposition to the new police, crime, sentencing and courts bill.
Hundreds gathered in Cardiff, Newport, Swansea, and Newtown to oppose the legislation which - amongst other things - will create stricter laws around protests.
The bill is set to be voted on in the House of Lords on Monday, January 17.
The anti-protest measures in the new bill provide police with the power to ban marches and demonstrations viewed to be "seriously disruptive", which can include being too noisy.

Demonstrators gathered on streets across Wales, joining protesters in cities all over the UK, including Bristol, London, Liverpool, Manchester, and Plymouth, to defend their rights.
David France, Extinction Rebellion activist, said: "These may have been some of the last legal protests we see in England and Wales.
"Boris Johnson’s Government knows they’re too corrupt to stay in power legitimately - just look at the party fiasco - so they’re basically breaking democracy so they can continue to profit from their positions, regardless of public opinion.
"This is how a democracy turns into a dictatorship, and the only thing that will stop it is the collective will of all of us."
Signs from those gathered read: 'Defund the police', 'Save our right to protest', and 'Democracy & freedom of speech is under attack'.
The 300-page bill makes a wide variety of changes to the justice system in England and Wales, from tougher sentences for killer drivers to provisions allowing court appearances over video conference.
Many aspects of the bill have caused controversy, including the expansion of police powers to deal with protests, more stop-and-search, and laws about encampments that critics - including human rights group Liberty - say will persecute Gypsy, Roma and Traveller communities in the UK.
Ann-Marie Evans, an activist for Gypsy, Roma and Traveller rights, said: "When I was a child, as strikes raged and interest rates soared, many people had their homes repossessed.
"That’s why my parents sold their house and bought us a boat. My parents and I would have been criminalised by section 4 of this PCSC bill.
"Unless the PCSC bill is voted down on 17th January, it will be our new authoritarian state law."
Cathy Brooks from Palestine Solidarity Campaign added: "In the 12 months since we formed Montgomeryshire Palestine Solidarity Campaign we have held a number of rallies and protests about what's happening in Palestine.
"Our right to carry out such peaceful demonstrations, to inform people who are willing to listen, is under threat should this legislation be passed."
