Arthur James Martin, Appellant v. State of Florida, Appellee

Summary

The court affirmed Martin’s first-degree murder conviction and death sentence after rejecting his challenges to the consideration of mental-health mitigation, the omission of substance-abuse mitigation, the HAC and CCP aggravators, and the constitutionality of Florida’s death-penalty scheme. The court also independently found sufficient evidence supporting the conviction and determined that the death sentence was proportionate. Chief Justice Labarga, joined by Justices Pariente and Perry, concurred in the result but would have held that the CCP finding was erroneous and harmless.
