If the SOM refers to School Districts as a Local Unit of Govt and preemption states that you CANNOT regulate in "any OTHER manner" I think preemption would apply.
The definitions used in other laws are irrelevant when a term is specifically defined within a law. If "local unit of government" had not been defined in the preemption law then it would be appropriate to look to other laws, court decisions, or the dictionary for a defintion. Unfortunately the legislature
did define it and their defintion for local unit of government,
for the purposes of preemption, does not include a school district so school districts aren't preempted. It doesn't make any difference that other laws define a school district as a local unit of government.
Why is this so hard for people to understand?
