Title:
European_Union_law

Context:
Fundamental rights, as in human rights, were first recognised by the European Court of Justice in the late 60s and fundamental rights are now regarded as integral part of the general principles of European Union law. As such the European Court of Justice is bound to draw inspiration from the constitutional traditions common to the member states. Therefore, the European Court of Justice cannot uphold measures which are incompatible with fundamental rights recognised and protected in the constitutions of member states. The European Court of Justice also found that "international treaties for the protection of human rights on which the member states have collaborated or of which they are signatories, can supply guidelines which should be followed within the framework of Community law."

Question:
The European Court of Justice cannot uphold measures that are incompatible with what?

fundamental rights recognised and protected in the constitutions of member states
