Eastern Electric, a subcontractor, sued Shoemaker Construction and project owners for failing to pay invoices over 100 days late on a Philadelphia condo conversion project. The court ruled that the owners' failure to pay when due was a material breach of the construction contract, excusing the contractor from further performance. The court awarded Eastern damages including unpaid balances, interest, and penalty interest, establishing that payment delays of this magnitude give contractors the right to stop work and recover damages.
