The Conservatives have described their plans to stop British laws being overruled by human rights judgements from Strasbourg as "viable and legal".
Justice Secretary Chris Grayling said if the Tories won the 2015 election, a new Bill of Rights would give UK courts and Parliament the "final say".
There should be no "legal blank cheque to take human rights into areas where they have never applied", he added.
But former Attorney General Dominic Grieve said the plans were flawed.
The Tory MP said they would be "difficult to implement" and risked "undermining" the UK's - and his own party's - tradition of upholding human rights.
Labour and the Lib Dems have said the proposals are politically motivated while the UK Independence Party claimed they were "worthless".
The Conservatives have pledged for a decade to scrap the 1998 Human Rights Act, introduced under the Labour government, which incorporates the European Convention on Human Rights into British law.

In his speech to the Conservative conference on Wednesday, David Cameron said if his party formed the next government, it would replace the Human Rights Act with a British Bill of Rights and Responsibilities.
The Tories have also said they would be prepared to exercise their right to withdraw from the European Convention if Parliament and the British courts could not veto laws from applying to the UK.
The Council of Europe, comprising European Convention member states, said it was "inconceivable" that the UK, as a founding member, could leave.
Ten cases where criminals made a mockery out of justice
KILLER DRIVER: Iraqi Aso Mohammed Ibrahim left 12-year-old Amy Houston to die ‘like a dog’ under the wheels of his car after knocking her down in Blackburn in 2003 while banned from driving. Twice refused asylum, he was never removed by the Home Office and after the killing, was allowed to stay in the UK after serving a mere four months in jail because he had fathered two children here, which judges ruled gave him a right to a ‘family life’. David Cameron wrote to Amy’s father Paul in 2010 pledging to abolish the Human Rights Act and ensure rights were ‘better balanced against responsibilities’.
RAPIST: William Danga was jailed for ten years for raping a 16-year-old girl. The 40-year-old Congolese asylum seeker, who raped and molested two young girls while fighting deportation after his release and is now serving a 15-year sentence, used the fact he has two children to stay in Britain.
WAR CRIMES SUSPECT: Serb Milan Sarcevic was accused of involvement in the 1991 Vukovar massacre of up to 300 men and women. The wounded Croat victims were beaten, executed and buried in a mass grave. A judge ruled evidence of his involvement was ‘not conclusive’ and did not warrant breaching his ‘strong family life’. The 62-year-old lives on a council estate in South-East London with his wife, daughter and granddaughter.
MURDERER: Kirk Dickson was given the right to become a father from behind bars. A 2007 ruling by the European Court of Human Rights allowed him to participate in artificial insemination treatment from inside prison. Another application by a further, unnamed inmate was approved in 2011 and several other applications have been made.
RAPIST: Mustafa Abdullahi – who held a knife to a pregnant woman’s throat as he raped her – was given permission to stay in Britain in December 2013 because of his family rights. The 31-year-old Somali failed asylum seeker was jailed for ten years in 2007 and ordered to be deported but immigration judges said it would breach his family rights – even though he does not have a wife or children in Britain – because his mother and other family members live in the UK.
VIOLENT MOTHER: A Bangladeshi woman jailed for five years for stabbing her baby daughter with a kitchen knife in East London in 2009 won the right to stay in Britain so she could rebuild her relationship with the child.
ROBBER: A Sri Lankan jailed for robbery in 2008 was allowed to stay as he had a long-term girlfriend. The 22-year-old’s lawyer argued he had ‘established a private and family life’.
RAPIST: Nigerian Akindoyin Akinshipe, 24, escaped deportation in 2011 when judges ruled he had a right to a private life here even though he has no wife or children. He had been jailed for raping a girl of 13 when he was 15.
BURGLAR: Wayne Bishop, 33, from Clifton, Nottinghamshire, was let out of prison in May 2011 after just one month of an eight month sentence so he could look after his five children on the grounds their rights were more important than those of his victims.
SEX OFFENDER: Mohammed Kendeh escaped removal to Sierra Leone despite convictions for robbery, burglary, arson and assaults on 11 women. An immigration judge ruled in 2007 that as Kendeh, 24, came to Britain aged six, and had almost no family in West Africa, he had effectively become ‘one of us’.
