Background
Michael Addison was convicted of capital murder in 2008 and sentenced to death. The New Hampshire Supreme Court affirmed his conviction and sentence after conducting the mandatory appellate review required by RSA 630:5, including a comparative proportionality review that found the death sentence neither excessive nor disproportionate.
While Addison’s later habeas case was pending, New Hampshire repealed the death penalty in 2019. The repeal applied only to persons convicted of capital murder on or after its effective date. Addison sought a renewed comparative proportionality review, arguing that the repeal made his existing death sentence excessive and disproportionate. The superior court concluded that the Supreme Court had exclusive jurisdiction over that statutory review and stayed the habeas matter while Addison pursued this original petition.
The Court’s Holding
The court dismissed the petition. It held that RSA 630:5, X and XI authorize only one comparative proportionality review, as part of the mandatory automatic appellate review of a capital-murder conviction and death sentence.
The statute requires automatic review within a specified, expedited time period and gives that review priority over other cases. Those features, the court reasoned, are incompatible with allowing parties to seek successive reviews after the initial appellate process is complete. The court also concluded that using a renewed review to account for the 2019 repeal would conflict with the legislature’s express decision to limit the repeal to persons convicted on or after its effective date. The court did not address the constitutionality of Addison’s sentence.
Key Takeaways
- RSA 630:5 permits one comparative proportionality review during the mandatory appellate review of a death sentence.
- New Hampshire’s 2019 death-penalty repeal does not apply to defendants convicted before the repeal’s effective date.
- The decision resolves only the statutory request for renewed proportionality review, not Addison’s constitutional claims in habeas proceedings.
Why It Matters
The decision forecloses an effort to use New Hampshire’s statutory proportionality-review procedure to reopen a death sentence already reviewed on direct appeal. It emphasizes that comparative proportionality review is a statutory appellate mechanism, not a constitutional requirement.
For pre-repeal capital defendants, the ruling confirms that the repeal itself does not create a statutory right to a new proportionality assessment. Any remaining challenges must proceed, if at all, through other available legal theories.
