Hamlin Township has an ordinance requiring property owners to keep their yards presentable. One requirement is that grass cannot be more than eight inches high. Residents complained to the town council that some property owners are letting their grass grow too high. The council instituted the following incentive program: Any property owner who violated this rule would receive a 5% reduction on their annual township property tax if they went 12 months without another violation. The program was very successful, as most previous violators maintained their grass at the proper height and will receive the tax break the next time taxes are due. As a result, the township is expecting to collect lower revenues and is planning to cut some services in order to meet its budget. Residents who never violated this township ordinance are not getting the tax break and are upset by the suggested cuts in services. They are suing the township, saying the incentive program was illegal and should not be honored. The court will likely rule that this incentive program is: 10 a. not enforceable, because the council is not offering anything of legally sufficient value. O b. enforceable only if the state also agrees to the property tax discount. 10 c. enforceable, because the council is offering something of legally sufficient value. O d. not enforceable, because it is asking property owners to do something they have a prior legal duty to do
