Dellinger argued that, after a state court found he had made an initial showing of intellectual disability, denying him a hearing on that claim violated the Eighth Amendment and the Fourteenth Amendment.
A Tennessee state court had already found that Dellinger made an initial showing of intellectual disability. Tennessee courts then used a procedural rule to prevent him from presenting that claim at a hearing.
The petition raised Eighth and Fourteenth Amendment questions about whether a procedural rule could prevent a hearing on Dellinger’s intellectual-disability claim.
