You said the decision had nothing to do with ECHR?
I've just explained that it does and why judges are overstepping their authority. They are determining UK government policy by relying on the possibility that an asylum seeker could be sent back to a country where they are mistreated - even though the UK government has a promise from the government of Rwanda this won't happen. For the tiny chance that it could happen - UK law and policy is decided by judges. A parliamentary system cannot abide judicial over reach. Parliament is sovereign, not the courts.
You have not explained why the judges are “overstepping their authority.”
You have expressed an opinion that the judges are “overstepping their authority.”
Until you learn to differentiate between fact and your opinion you will continue to make erroneous statements.
However, since you’re here; could you
explain how it is that the risk of being sent back to their own country and mistreated is, as you state,
tiny?
