Genesis Harper was convicted of armed robbery and, as a recidivist, received life without parole because Georgia law required the maximum punishment for the offense of conviction. She argued that the armed-robbery statute’s alternatives of life or a term of years created ambiguity, requiring the rule of lenity and a maximum sentence of 20 years. The Court of Appeals affirmed, applying binding precedent that treats life imprisonment as the maximum authorized sentence and a term of years as a lesser alternative. Because the statute was not ambiguous in the relevant sense, lenity did not apply.
