Stephen Johnson Field,
State of Louisiana Nelson v. Police Jury of the Parish of St…
“ By the obligation of a contract is meant the means which, at the time of its creation, the law affords for its enforcement. The usual mode by which municipal bodies obtain the funds to meet their pecuniary engagements is taxation. Accordingly, when a contract is made upon the faith that taxes will be levied, legislation repealing or modifying the taxing power of the corporation, so as to deprive the holder of the contract of all adequate and efficacious remedy, is within the constitutional inhibition. ”
