The author proves by a simple character argument that there is a unique tensor invariant of degree 3 for the Weil representation of \(SL_ 2(q)\), where \(q\) is an odd prime power. He also investigates the explicit form of the invariant. The paper generalizes, simplifies and corrects results of an earlier paper [J. Algebra 72, 146-165 (1981; Zbl 0479.20020)].
