Whether or not a sentence is appropriate for the crime convicted of and the character of the person convicted is a frequent issue on appeal. Less frequently there is an issue of sentence disparity between co-actors or co-accuseds.
The recent ACCA decision in United States v. Martinez (Sept. 2017), lays out the law fairly well on how to analyze and argue the issue.
In this case we hold appellant’s sentence was appropriate despite his assertion of sentence disparity with his coactor. While there is a not a bright-line test for when a sentence is highly disparate, the law is clear that sentence disparity is only one of many aspects of sentence appropriateness. We therefore hold that even if appellant’s sentence was highly disparate with his coactor’s sentence, appellant’s sentence was still appropriate for his crimes.
