Yes, but in this case a different (much dumber) system had been established for decades without objection it seems. That's different than just having regular, official elections with just one candidate, which is what they should have done in the first place. We don't know who would have won if it was a normal, two-candidate election.
This going to court is a good thing because a) anyone could have filed the paperwork and won by default, including someone who would abuse the position and be really terrible for the town and b) this is certainly the end of the unofficial-official system they've had and might bring bad stuff to light. But keep in mind that the article's coming on very strong because they mostly cite the prosecution.
