Ex Parte Dallas Alan Martin, Jr.

Summary

The Court denied the applicant's habeas claim, holding that the federal double‑jeopardy doctrine articulated in Burks and Greene does not apply to convictions based on a voluntary guilty plea, and therefore the prior 1973 conviction may be used for sentence enhancement. The decision overturns the earlier order granting relief and affirms the life sentence, with two dissenting opinions contesting that conclusion.
