The coalition government has announced it is to create a commission to review the UK's Human Rights Act.
It comes as two terror suspects, Abid Naseer and Ahmad Faraz Khan, successfully appealed against deportation to Pakistan.
A special immigration court said Mr Naseer was an al-Qaeda operative, but neither man should be deported.
The Tories had proposed replacing the Human Rights Act with a "British Bill of Rights". The Lib Dems oppose this.
The Human Rights Act 1988 incorporated fundamental rights enshrined in the European Convention of Human Rights into UK law.
These included the right to life, the right to family, freedom from torture and the right to a fair trial.
