is the old order legislation relevant to new constitutional order?

It depends on the specific legislation in question and how it aligns with the principles and values of the new constitutional order. In many cases, old order legislation may no longer be relevant or may conflict with the principles of the new constitutional order, and therefore may need to be amended or repealed. However, there may also be instances where certain old order legislation can still be relevant and compatible with the new constitutional order. Ultimately, it is up to the legal and constitutional authorities to determine the relevance of old order legislation in the context of the new constitutional order.
