In a way that relates to the process of making or enacting laws.
The new policy was implemented legislatively to ensure compliance with the law.
Legislatively → It is formed from "legis" (from Latin *legis*, meaning law) and "-lative" (from Latin *latus*, meaning brought or carried). The word "legislatively" refers to the manner in which laws are brought into effect or enacted.
Think of 'law' ('legis') being 'brought' ('latus') into action — that's why legislatively means in a manner related to law-making.
