Answer:
Most definitely, Tony would lose due to the integration clause.
Step-by-step explanation:
An integration clause requires a short paragraph to be inserted into a written contract to confirm a final deal between two sides.
Since drafting a written contract, it may fail to be fully checked by one of the parties involved to ensure that all provisions are included and that both parties sign the contract, which Tony failed to consider.
If this happens, one party could contend that the other failed to uphold a particular condition or phrase that they consented to verbally.
