The City argued that the contract was not "properly executed" because it was not signed by the mayor and city controller. Id. at 446. The City relied on the 1905 City Charter. Id. This court held that a properly executed contract was established by the combination of (1) the contract document; and (2) the City Council's passage of an accompanying motion that constituted "the last step needed to complete the written contract between the parties." Id.
