Morrison Waite,
United States v. County of Macon…
“ If the purchaser in this case had examined the statutes under which the county was acting, he would have seen what might prove to be difficulties in the way of payment. As it is, he holds the obligation of a debtor who is unable to provide the means of payment. We have no power by mandamus to compel a municipal corporation to levy a tax which the law does not authorize. We cannot create new rights or confer new powers. All we can do is to bring existing powers into operation. ”
