An anti-hunt MP has urged police to seize horses from hunters if they defy the ban and kill foxes with more than two hounds.
Pro-hunt groups call Mr Simpson's plan "ludicrous"
Nottingham South MP Alan Simpson said enforcement is a key to making sure the new Hunting Bill is upheld.
Mr Simpson said: "People cannot be given the idea that they can flaunt the law with impunity."
But the Countryside Alliance says seizing horses would create logistical problems for the police.
"We hear a lot of bravado from the hunt that says we are not going to take any notice of it (the new law)," said Mr Simpson.
"Parliament should not pass laws it does not intend to enforce - and doesn't give the police the methods to enforce."
Countryside Alliance spokesman James Bates said the MP's suggestion is "ludicrous".
He said: "What are they going to do - get paddy wagon for horses? Where do they keep the horses if they seize them?
"I don't think you will find any police officer taking action like that.
"There is a clear provision in the law that allows police to seize any instrument used with intent to break the law - so the police already have the power."
Steve Green, Chief Constable of Nottinghamshire Police, said previously while those breaking the law would be dealt with, resources were limited.
He added: "The priorities for my officers are to arrest burglars, robbers, thieves and murderers and protect people from becoming victims of crime."
