We discuss the emergence of an orthogonality catastrophe in the response of a composite fermion liquid as the filling factor v approaches 1/2m, where m = 1,2, 3 . . .. A tunnelling experiment is proposed in which dramatic changes in the I-V characteristic should be observable as ν is varied. Explicit I-V characteristics calculated within the so-called modified random phase approximation, are provided for ν = 1/3 → 1/2.
