Legal Question in Civil Litigation in Indiana

The answer is probably yes. Most towns have ordinances which allow them entry into even fenced property to remedy a situation. If not, then the law usually allows a governing authority to enter to remedy a nuisance or hazard. If a town fire department has the right to enter a fenced area to put out a fire, by analogy, it arguably has a right to enter to solve other categories of problems. And if the town obtained court permission, there isn't much that you can argue other than in court.
