In brief
Overview
Petitioners argue that the adequate State grounds doctrine should not strip State courts of their equitable power to excuse procedural defaults, but only to prevent discrimination against Federal claims.
According to Petitioners, they contend that the rule applied to the defendant was discretionary, not an inadequate procedural default.
According to Petitioners, they further argue that the State rule gave the defendant reasonable notice, so the State ground cannot be thrown out in Federal court for inadequacy.
According to Commonwealth, according to the petitioner (the Commonwealth), it wants the Court to change the adequate State grounds doctrine so that Mr. Kindler may be executed without further court review of his constitutional claims.
Background and question before the Court
According to Petitioners, the case concerns whether the adequate State grounds doctrine requires a State procedural rule to be “adequate” when the rule is discretionary, and whether such discretion precludes Federal courts from reviewing constitutional claims.
