Isbell asked the Supreme Court to review the Fifth Circuit’s handling of his request for permission to appeal his federal challenge to imprisonment.

Question presented

1. Whether the 5th Circuit erred in directing matters directly towards the underlying merits in its C.O.A. analysis? 2. Whether a C.O.A. should issue because reasonable juris could debate that: (a) Isbell was denied his substantial right to effective assistance of counsel when his trial attorney abandoned exclusion of evidence related to a 4th amendment violation; and (b) the federal District Court erred in adopting a 'preponderance' standard to dismiss this 'Strickland' issue? 3. Whether a C.O.A. should issue because reasonable jurist could debate that: (a) Isbell was denied his substantial right to assistance of counsel when his trial attorney accused him of committing the 'only' charged conduct - entirely failing to act as the goverments adversary - during closing summarization, and (b) the federal district court erred in failing to review this issue under the proper 'CRONIC' standard?
