The government are considering totally legal ways of bypassing the obfuscation of the original intent of "human rights law" by well funded barristers and judges with zero regard to the cost to our country by their shenanigans :
Britain is preparing to opt out of major parts of European human rights laws, risking an explosive new row with the EU.
Boris Johnson's aides and ministers are drawing up proposals to severely curb the use of human rights laws in areas in which judges have "overreached".
The plans under discussion include opt-outs from the Human Rights Act, which could prevent many migrants and asylum seekers from using the legislation to avoid deportation and protect British soldiers against claims relating to overseas operations. The Act allows British courts to apply the European Convention on Human Rights (ECHR).
The move sets up a major new confrontation with the EU, which has been demanding that the UK commits to remaining signed up to the ECHR and keep the Human Rights Act in place as the price of future "law enforcement co-operation" between the bloc and Britain.
None of which makes little difference except maybe help in sending them back but not sure to where as under International law we cant send them back to France and without their passports which country do we try and deport them to?
The United Nations Convention of the Law of the Sea covers the migrants crossing the sea and what happens once they are in our territorial waters. Nothing to do with the EU btw.
Or are you supposing we withdraw from UNCLS as well?
