 Thompkins appealed his conviction on grounds that included suppression of his admission - that he had invoked and not waived his right to remain silent - and deficient representation related to improper jury instructions , but the Michigan Court of Appeals rejected Thompkins ' Miranda claim . Thompkins then filed a writ of habeas corpus in federal District Court but it denied his request . However , the United States Court of Appeals for the Sixth Circuit reversed the District Court 's decision , holding that the state court was unreasonable in finding an implied waiver of Thompkins ’ right to remain silent .
