With no explanation, chose the best option from "A", "B", "C" or "D". except by writ of injunction, and no bill of review shall be filed after two years have elapsed from the date of such decision, order, or judgment. Former Tex. Prob. Code § 31 (current version at Tex. Estates Code § 55.251). In contrast to equitable bills of review, section 31 has been interpreted to require a showing of “substantial error” in a prior decision, order, or judgment. See, e.g., Nadolney v. Taub, 116 S.W.3d 273, 278 (Tex. App. — Houston [14th Dist.] 2003, pet. denied) (“The purpose of a section 31 bill of review is to revise and correct errors, not merely to set aside decisions, orders, or judgments rendered by the probate court.”); McDonald v. Carroll, 783 S.W.2d 286, 288 (Tex. App. — Dallas 1989, writ denied); cf. Norton v. Cheney, 138 Tex. 622, 161 S.W.2d 73, 74 (1942) (<HOLDING>). Fidelity and Valdez contend the Legislature
