William O. Douglas,
Wisconsin v. Constantineau — Opinion of the Court
“ It is no answer to contend that there is no ambiguity in the Wisconsin statute and hence no need to abstain; in Reetz the Alaska statute could not have been more plain, or less susceptible of a limiting construction. Yet, in furtherance of this Court's firm policy to steer around head-on collisions with the States by avoiding unnecessary constitutional decisions, we reversed the District Court and remanded with instructions to stay its hand while the litigants exhausted state court remedies for resolution of their challenge to the statute. ”
