Texas Supreme Court

In R.R. Street & Co. Inc. v. Pilgrim Enterprises, Inc., 166 S.W.3d 232 (Tex. 2005), a “case of first impression” under the Texas Solid Waste Disposal Act, Hicks Thomas won a unanimous reversal of an unfavorable intermediate appellate decision.

In King Ranch, Inc. v. Chapman, 118 S.W.3d 742 (Tex. 2003), Hicks Thomas founder John Thomas served as co-lead counsel in obtaining a unanimous reversal of an intermediate appellate decision that would have unsettled title to the storied King Ranch in South Texas.
