Illegal Migration Bill

When my noble friend was replying to the noble Lord, Lord Carlile, he said that the ECHR memorandum set out precisely which articles of the convention had that effect and which clauses in the Bill were compatible or not, and, as he says, different rights are listed. But what is the status of that definitive document? He says it is the answer to the noble Lord’s question, but what is its status? Presumably it does not have legal effect in itself.
