Does county wide appellate binding precedent overrule local ordinances?

A lot of times the written decision of a higher court regarding a town without an ordinance contradicts a town that has said ordinance on the books. So in court would you prevail if you cite appellate case law contradicting statutory law? For example: town A has ambiguous law so high court creates case law town B does have a narrow law on books So if I go to court fighting town b law using binding written decision from a case that originated from town a would I prevail.
