Adequate argument?

In an echo (pun intended) of the Flakes litigation, the panel majority and a concurrence disagreed as to whether the appellant had adequately briefed its arguments; the majority finding that they had been appropriately presented and the concurrence holding a different view. For interested practitioners, the full text of the pertinent argument (relating to whether the underlying proceedings were an impermissible collateral attack on an earlier judgment) is reproduced in the concurrence. Eco Planet, LLC v. Ant Trading, 05-19-00239-CV (Nov. 16, 2020).
