Sometimes it's mostly about taking an interest, reading or understand the legislation, and making a really good case and argument to the government.

I don't think I can claim credit because I'm sure I wasn't the only one, but it took 3 or 4 emails to a couple of legislator offices to get some policy changes. In my case it might've just been small enough (no news coverage, basically only a small number of people were aware of a regulatory memo), the first time or two they just kicked the can down the road deferring the implementation, until ultimately they reversed course. And my part was just laying out a very strong case for why the particular situation was unfair, how many people would be impacted (voters), etc. Nothing confrontational, just laying out the argument.
