How have courts interpreted section 1170.95 of the California Penal Code?

Penal Code section 1170.95, subdivision (a) provides, in plain language, that only persons "convicted of felony murder or murder under a natural and probable consequences theory" may file a petition seeking resentencing. "When we interpret statutes, giving effect to legislative purpose is the touchstone of our mission." (People v. Valencia (2017) 3 Cal.5th 347, 409.) "The text of the statute is integral to our understanding of the statute's purpose." (Ibid.) "We must take 'the language . . . as it was passed into law, and [we] must, if possible without doing violence to the language and spirit of the law, interpret it so as to harmonize and give effect to all its provisions.' " (Id. at pp. 409-410.)
