"Thrown Out" was a vague term but would there be no legal recourse to require it to be changed.
Republic was in breach of contract with Delta, and Republic cited lack of pilot as a reason for not being able to fulfill the contract. Therefore the TA will be changed because it adversely affected Republic's ability to complete the contract.
