In brief
Overview
According to Robert B. Dunham, david Allen Sattazahn is asking the Supreme Court to decide whether his first capital‑trial judgment of life bars Pennsylvania from seeking the death penalty in a second capital trial.
According to Ms. Dougherty (Respondent), according to Ms. Dougherty (Respondent), the Commonwealth argues that the life sentence created by the first trial gives the defendant a protected liberty interest that survives appeal.
Background and question before the Court
Pennsylvania was afforded one fair opportunity to sentence Mr. Sattazahn to death, and the jury rendered a verdict in accordance with the trial‑court instructions.
The central double‑jeopardy question is whether the first judgment of life precludes the Commonwealth of Pennsylvania from seeking and obtaining the death penalty in a second capital trial.
What each side argues
Petitioner Position
According to Robert B. Dunham, the petitioner contends that the first capital‑trial judgment of life precludes a second death‑penalty trial under the Double Jeopardy Clause.
Respondent Position
According to Ms. Dougherty (Respondent), according to Ms. Dougherty (Respondent), the Commonwealth argues that the life sentence creates a liberty interest that survives appeal because of a special interest in finality.
According to Ms. Dougherty (Respondent), according to Ms. Dougherty (Respondent), the respondent further maintains that a life sentence imposed after a hung jury is not an acquittal and therefore does not trigger double‑jeopardy protection.
