error. The indictment in question states that the grand jury was "organized as such at the JULY/SEPTEMBER Term A.D. 2003 of the 159TH Judicial District Court" of Angelina County, Texas. That court has no "JULY/SEPTEMBER Term." See TEX. GOV'T CODE ANN. § 24.302 (Vernon 2004). Further, any such term would have expired before the alleged crime was committed and before the grand jury handed down its indictment. See TEX. GOV'T CODE ANN. § 24.012 (Vernon 2004). Therefore, we requested that the parties address whether it is possible from the appellate record to conclude that the individuals who rendered this indictment were still members of a grand jury. SeeWebb v. State, 161 Tex. Crim. 442, 444-45, 278 S.W.2d 158, 159-60 (1955). We also requested that the parties address whether an error of this type must be preserved for appellate review. After considering the briefs of both parties, we hold that an error in the designation of the grand jury's term is an error of form. SeeCarawayv. State, No. 10-04-00364-CR, 2005 WL 3005669, at *1 (Tex. App.-Waco Nov. 9, 2005, no pet.) (mem. op., not designated for publication); Ragston v. State, No. 01-99-01091-CR, 2000 WL 1434246, at *1 (Tex.

"If the defendant does not object to a defect, error, or irregularity of form or substance in an indictment or information before the date on which the trial on the merits commences, he waives and forfeits the right to object to the defect, error, or irregularity and he may not raise the objection on appeal or in any other postconviction proceeding." TEX. CODE CRIM. PROC. ANN. art. 1.14(b) (Vernon 2005). Therefore, this error is of the type that may be forfeited by inaction. SeeMendez v. State, 138 S.W.3d 334, 340 (Tex. Crim. App. 2004) (describing forfeitable rights); see alsoCaraway, 2005 WL 3005669, at *1; Ragston, 2000 WL 1434246, at *1. Although courts of appeals may have the discretion to review unassigned error, seeCarter v. State, 656 S.W.2d 468, 468-70 (Tex. Crim. App. 1983), they "c
