In Gilchrist v. O’Keefe, 260 F.3d 87 (2001), Sotomayor wrote for the panel, which rejected an inmate’s claim that he was unconstitutionally deprived of his right to counsel during his state sentencing proceeding when the trial judge declined to appoint a new attorney to replace the attorney who withdrew after the inmate punched him in the head.

See the original source, as well as the decision itself.

It is worth highlighting that the fact that the deprivation occurred during “state sentencing” is critical to the opinion, as 28 U.S.C. § 2254(d)(1) (the relevant clause in US code) prevents granting relief in response to a state proceeding, assuming the decision was not “contrary to clearly established Federal law” (which, the decision notes, it was not). As a consequence the decision need not (and does not) reach any question along the most obvious line suggested by the quote, at least not outside of dicta (with which, tangentially, I am not particularly inclined to disagree) — an example of how legal decisions need not be as obvious as they seem, and an example of how common sense may play little to no part in the legal reasoning of a “common-sense ruling”.
