A developer contracted with a general contractor to build an office building, and completion of the building was two years late. The developer filed a breach of contract action in federal district court against the general contractor, seeking damaged caused by the delay. The general contractor filed a third-party claim against a major subcontractor, claiming that the subcontractor caused any delay and should be liable to the general contractor for anything the general contractor has to pay the developer. The subcontractor believes that the developer interfered with the subcontract and that the developer's interference caused not only the delay but also substantial cost overruns for the subcontractor.
May the subcontractor assert a claim in the pending action against the developer seeking payment for the cost overruns?
