Constitutional role

The Constitution of Luxembourg defines the grand duke's position:

After a constitutional change (to article 34) in December 2008 resulting from Henri's refusal to sign a law legalizing euthanasia, laws now take effect without the grand duke's assent.[2] As a result, the grand duke no longer has any formal role in the legislative process, but his task to promulgate the law as chief executive remains.
