37In that regard, it is clear from Article 52(1) of the Charter that any limitation on the exercise of that right must be provided for by law and must respect the essence of that right and be subject to the principle of proportionality. In so far as the Charter contains rights which correspond to rights guaranteed by the ECHR, Article 52(3) of the Charter provides that the meaning and scope of those rights must be the same as those laid down by that convention, while specifying that EU law may provide more extensive protection. For the purpose of interpreting Article 6 of the Charter, account must therefore be taken of Article 5 of the ECHR as the minimum threshold of protection.
