UK courts cannot set aside legislation because that would undermine parliamentary sovereignty.
Parliament can make any law it so pleases.
ECHR was domesticated partly because parliament was overmighty.

Lord Bridge on this case. His obiter dicta,
” If the supremacy within the EEC of community law over the naitonal law of member states was not already inherent it was already well established in the jurisprudence of the court of justice long before the UK joined the community. Whatever limitation on its sovereignty that Parliament accepted when it passed the 1972 act was entirely voluntary. Under the terms of the 1972 act it was always clear that it was the duty of the UK court when delivering final judgment override any national law that was incompatible with any directly enforceable rule of community law. When decisions of the ECJ have exposed areas of UK statute law that have failed to implement community directives Parliament has always loyally acted to make appropriate and prompt amend. Thus there is nothing novel in according supremacy to community law in those areas to which they apply. National courts must not be inhibited from granting the appropriate relief and injunctions. It is no more than a logical recognition of that supremacy. ”
