While Franklin Interiors is analogous to this action it is nonetheless contradistinet. The agreement at issue herein involved a state agency and an independent contractor. The agreement contained no express proviso conditioning the contract on the approval of parties outside the contract. Here, unlike Franklin Interiors, we are asked to determine when a government unit becomes contractually obligated to a contractor — whether, at the time the contract is awarded or when the contract has been formally signed. Thus, the analysis employed to resolve this matter is distinct from that employed by the Board.
Notwithstanding general principles of contract law, in determining the validity of a state agency contract three matters must be considered. First, had the state agency the power to enter into the contract, and if so, whether it was entered into by the proper entity,7 i.e., department, board, committee, officer or agent. Second, was the contract entered into by proper mode, ie., does a statute govern contract formation.8 Third, whether it is evident that a contract was formed, and if so, whether it must be in writing, and if so whether the writing is contingent upon other conditions, such as, signatures or approvals.9 If the mode of contracting is not prescribed by statute, a state agency may make a contract in the same manner as other corporations or partnerships or individuals.10
The theory of the case advanced by the LCB relies on Franklin Interiors to support the theory that the parties, by including countersignatures in the agreement, mutually assented to the condition that obtaining the countersignatures was a necessary component of the contract. In contradistinction, Shovel advances the argument that the signature of the comptroller and budget secretary are superfluous; therefore, a binding contract was formed when the signatures of the LCB Chairman, LCB Chief Counsel, and the President of Shovel were affixed to the contract.
“Mutual assent is essential to the formation of a binding contract,” and “must be manifested by one party to another.” 17A Am.Jur.2d § 28. “Assent in the sense of the law is a matter of overt acts and expressions.” Id. In this Commonwealth it is well established that “parties may bind themselves contractually prior to the execution of a written document through mutual manifestations of assent, even where a later formal document is contemplated.” Krause v. Great Lakes Holdings, Inc., 387 Pa.Superior Ct. 56, 563 A.2d 1182, 1185 (1989). “If the parties agree upon essential terms and intend them to be binding, ‘a contract is formed even though they intend to adopt a formal document with additional terms at a later date’.” Johnston v. Johnston, 346 Pa. Superior Ct. 427, 499 A.2d 1074 (1985) (citation omitted). Where however the parties contemplate that their agreement cannot be considered complete before it is reduced to writing, no contract exists until the execution of the writing. Essner v. Shoemaker, 393 Pa. 422, 143 A.2d 364 (1958).
The Board believed the LCB had expressed its intent not to be contractually bound to Shovel until the agreement at issue was approved and executed by all designated signatories. In considering the past dealings between the parties, and written correspondence accompanying the agreement, there is substantial evidence to support that position.
The Board rejected Shovel’s contention that the sole reason for signature lines for
