Langlands' analytic continuation and functional equation conjecture for automorphic L-functions

Let $F$ be a number field, let $\mathbb{A}$ be its ring of adeles, let $G$ be a connected linear algebraic group defined over $F$, let $\pi$ be an automorphic representation of $G(\mathbb{A})$, and let $r$ be a finite-dimensional representation of the Langlands dual group ${}^{\mathrm{L}}G$. The associated Langlands $L$-function is denoted by $L(s,\pi,r)$. Langlands' conjecture. The $L$-function $L(s,\pi,r)$ has a meromorphic continuation to the whole complex plane with only finitely many poles, and it satisfies a functional equation relating $s$ to $1-s$. This is a foundational analytic expectation for automorphic $L$-functions and generalizes the continuation and functional equation known for classical zeta and Dirichlet $L$-functions. The candidate is not accompanied by evidence of resolution in the supplied text.
