In G.T. Leach Builders, LLC v. Sapphire V.P., LP, 458 S.W.3d 502 (Tex. 2015), the Court concluded that sub-contractors who were not signatories to a general contractor's construction contract could not compel arbitration because the claims against them did not require enforcement of the general contract and could stand alone under the sub-contract. Id. at 527-30. The Court noted that the plaintiff's claims in that case derived from "separate alleged agreements." Id. at 529.
