In addition to the modifications that pertain to all habeas corpus cases, AEDPA enacted special review provisions for capital cases from states that enacted quality controls for the performance of counsel in the state courts in the post-conviction phase. States that enacted the quality controls would see strict time limitations enforced against their death-row inmates in federal habeas proceedings coupled with extremely deferential review to the determinations of their courts regarding issues of federal law. Only Arizona has qualified for the additional provisions, but it has not been able to take advantage of them because it has not followed its own procedures.
