Plaid Cymru’s Adam Price said his party “sympathises with the general aim of the bill”, but raised concerns over part of the legislation involving sharing information with international organisations to help fight crime.
The law would give powers both the UK and Welsh governments to set regulations over the information sharing, which in the case of the Welsh government could include wildlife and environmental offences.
But a cross-party committee criticised the prospect of allowing the UK government to set rules in a devolved area, something the Welsh government argued would be needed to implement international agreements.
Price said: “Goodwill is not law, a promise is not a safeguard, and the current relationship between the two governments, even when they’re made up of the same party, cannot be described as one of parity of esteem.”
He later accused Labour of not standing up for Welsh interests, adding: “Wales will not quietly surrender its powers.”
Reform’s Laura Anne Jones told the Senedd that while her party supported the legislation’s general principles, “we do not believe that the crime and policing bill goes far enough in effectively tackling crime”.
Altaf Hussain for the Conservatives said his party opposed the consent motion, raising complaints about artificial intelligence, facial recognition and non-crime hate incidents.
The consent motion was rejected with 25 Labour Members of the Senedd (MSs) voting for, 27 MSs voting against, and no abstentions.
Following the vote, Deputy First Minister Huw Irranca-Davies said: “When there was a choice to vote to make Wales a safer place, Plaid and the other opposition voted against it.”
“When there was a choice between backing tougher action on crime and creating a constitutional row, Plaid chose the row.”
The last major legislative consent motion (LCM) in Senedd was passed in February over how Wales would implement the legalisation of assisted dying, with Labour supporters of the legislation saying they would amend the bill – which is currently being scrutinised in the House of Lords – if the Senedd vote was lost.
