The generic Arthur packet conjecture

Let $\psi$ be an Arthur parameter, let $\varphi_{\psi}$ be its associated Langlands parameter, and let $\Pi(\varphi_{\psi})$ be the $L$-packet associated to $\varphi_{\psi}$. A representation is generic with respect to a Whittaker datum if it admits a Whittaker model for that datum. Generic Arthur packet conjecture. If $\Pi(\varphi_{\psi})$ has a generic member with respect to some Whittaker datum, then $\varphi_{\psi}$ is tempered. This conjecture has been proved for any quasi-split group under the equality of Langlands–Shahidi and Artin $L$-functions, with further progress for classical and general spin groups, but remains open in the stated generality.
