Gonzales v. North Township of Lake County
In Gonzales v. North Township of Lake County, 4 F.3d 1412 (7th Cir.1993), the Seventh Circuit rejected a claim of taxpayer standing, because there was no evidence of an expenditure of tax revenue solely on the challenged activity:
In this case, however, the plaintiffs' claim is undercut by their inability to show that tax revenue is spent for the crucifix. The Township did not use government money to buy the crucifix (it was donated). The Township does not use government funds to maintain the crucifix (it just exists, maintenance free). And although Township funds are spent maintaining the Park areas surrounding the crucifix, this cost would be incurred with or without the presence of the crucifix. Without evidence of expenditure of tax revenues, the plaintiffs cannot claim standing by virtue of their taxpayer status. Id. at 1416.
