THE AI-ASSISTED CRITIQUE
The court’s reliance on acquiescence and the parties’ course of dealing to resolve the contractual ambiguity is legally sound but may be criticized for its potentially harsh application against the employee, Kriedt. By emphasizing that Kriedt operated under a prior similar contract and failed to object at signing, the court effectively binds him to the employer’s internal accounting practices, which artificially inflated “gross receipts” through mere inter-departmental transfers. This approach prioritizes business certainty and the objective manifestation of intent over a substantive inquiry into whether the accounting method reflected the true economic output of the printing department. While the rule that parties’ post-formation conduct aids interpretation is well-established, its application here risks endorsing a formalism that could permit dominant parties to embed unfavorable terms through opaque bookkeeping, leaving less sophisticated contractors with little recourse if they do not immediately challenge an ambiguous clause.

The decision’s reasoning implicitly rests on the doctrine of contra proferentem, yet it inverts its typical protective function. The ambiguity in “gross receipts”—whether it meant revenue from external sales or included internal paper transfers—was created within the business controlled by McCullough & Co. Ordinarily, such ambiguities are construed against the drafter. However, the court sidesteps this principle by treating Kriedt’s silence as adoption of the company’s interpretation. This creates a problematic precedent: a party with superior knowledge of internal systems can draft an ambiguous profit-sharing term, apply a self-serving interpretation operationally, and then invoke the other party’s acquiescence as ratification. The court’s dismissal of the argument that the paper transfers were a “mere device” for inventory control, rather than genuine receipts, underscores a formalistic view of contract interpretation that may disregard economic substance.

Ultimately, the holding underscores the critical importance of explicit contractual definitions in complex commercial arrangements, especially those involving profit-sharing with embedded costs. While the outcome is defensible under traditional contract law principles focusing on the parties’ manifested intent, it highlights a vulnerability for employees or independent contractors operating within a larger entity’s ecosystem. The court’s mention of additional “gratuities” paid to Kriedt, though cut off in the text, suggests an unspoken equitable consideration, but it does not mitigate the legal rule established: in the face of ambiguity, operational practice and silent acquiescence can crystallize a term’s meaning, even if that practice appears economically unreasonable upon later scrutiny. This places a heavy burden on the non-drafting party to conduct immediate due diligence and negotiation, a burden often impractical in employment or dependent contractor relationships.
