We have the two tags legislation and legislative-process, which have very similar excerpts and IMHO discuss the same thing:
legislative-process (61 questions):
Questions about the processes to create laws in different jurisdictions.
legislation (43 questions):
Questions relating to the process of making or enacting laws.
I propose to merge the tags and to make legislative-process a synonym of legislation.
Btw: We have nine questions with both tags.
