under this court's controlling process and the privately least hangars and whiteside county airport were not exempt from taxation because they were not used exclusively for public purposes this matter can begin and in the marshall county case because it is indistinguishable from this matter although in that case the court was faced with the issue of airplane tied down leases the court noted that there is no factual distinction between private hangar leases and private airplane tied down and there is no reason for this court to overrule marshall county as it has been expressly le intact by the illinois supreme court in the harrisburg raleigh decision in that case the court distinguish between the role of the airport authorities purposes exemption which can include private uses and the narrow municipal property exemption which applies only to property that is used exclusively for him purposes and not least to private parties and this is diction is logical as the court noted because if the public purposes exemption and the airport authorities purposes exemption were synonymous there would be no need for a separate airport authority exemption and can the general municipal corporation that has to be created by contention and election and it serves a larger population there is a territorial population requirement for forming and her port authority and it's governed by an appointed board of commissioners and depending on the population of the territory that are served airport authorities in this area including the quad cities international airport  airport in rockford these are larger airports that serve a larger population it has to be exclusively for public purposes yes no the form the court has has looked at that as primarily for a public purpose so for example in the franklin county that the air workforce cites the court looked at whether the reese's there at the hotel used the restaurant use was primarily for a public purpose and even though there was some private usage the private uses dominate the hangar is being leased to a private party for private storage of their private aircraft and the airport itself serves us small group of people it does not have a regularly scheduled airline as it provides simply for flying instruction and radio maintenance and charter services so the population that is  served is much smaller than was the case and wrongly conservancy district and so the referee properly distinguished those two cases finding that any public benefit here was secondary to the primary private what it does facilitate the use of the airport but that doesn't make it a public purpose at most that would make it an airport purpose and the stipulation that the airport board is relying on what all they do is delay in essence that these hangars sermon that serve the same purposes as the airport authority hangars but the problem is this airport does not get the benefit of the airport authority purposes exemption which is broader and so the fact that it may the silicate use of the airport by these private parties doesn't make it a public purpose even if it would make it used by the airport is not relevant to the analysis as court stated in marshall county in stating that the fine line there that was leased was not used for public purposes even though the income from the leas not just taking money out of one pocket and putting it back into your left pocket there are there may be other  just for the two thousand and seven times  raised with respect to just a smidge question with respect to the issue of the where the monies go in this case we are talking about a local property tax at the time the allocation for exemption was made substantial relationship to the purpose the public purpose the fact is leased out doesn't change it stays exempt now where else do we see that language we see that language in that harrisburg  because they are scared or quarks about real and substantial relationship to the purpose of the airport authority i assume in that i see no distinction as we've argued in this case from the beginning there's no distinction between how  in marshall county at least from reading the opinion i can't speak for what the justices thought but we really then they may rest the issue of high down areas not high down there is an outside area an airplane to be tied down it's not much different than  possible first i want to emphasize again the standard of review here if you are looking at this case in comparison to the franklin county case please keep in mind that there is a clear error standard what the referee found here is that the uses here that were facilitated by the hangars were primarily private and that is not clear really erroneous although it might have been possible to come to a different conclusion what the referees found is that these hangar bays are being used by private people to store their private aircraft for their own individual private use is it true the only to own room but there's a difference your honor because we are we are looking at the use of the specific property at issue we're not looking at the runway we're not looking at the airport the rest of the airport land we're looking at the specific use of these defined hangar bay and so the runway itself is used for a public purpose in that the the public can come in and use those runways the public cannot come in and use these private issue here and there was no clear error in finding that those specific pieces of property at issue are used primarily for private purposes second i wanted to answer your question that the general assembly has decided and although it may not seem fair to treat them differently the general assembly has decided to do that and if they want treatment as an airport authority they need to go through the steps of incorporating as an airport before it was built in the general sense please authority to distinguish between these two different types of airports and to treat those private leases differently under
