14 CITIZENS UNITED v. FEDERAL ELECTION COMM’N Opinion of STEVENS, J. lenge that dropped out of this case 20 months ago. Narrower Grounds It is all the more distressing that our colleagues have manufactured a facial challenge, because the parties have advanced numerous ways to resolve the case that would facilitate electioneering by nonprofit advocacy corpora­ tions such as Citizens United, without toppling statutes and precedents. Which is to say, the majority has trans­ gressed yet another “cardinal” principle of the judicial process: “[I]f it is not necessary to decide more, it is neces­ sary not to decide more,” PDK Labs., Inc. v. Drug En forcement Admin., 362 F. 3d 786, 799 (CADC 2004) (Rob­ erts, J., concurring in part and concurring in judgment). Consider just three of the narrower grounds of decision that the majority has bypassed. First, the Court could have ruled, on statutory grounds, that a feature-length film distributed through video-on-demand does not qualify as an “electioneering communication” under §203 of BCRA, 2 U. S. C. §441b. BCRA defines that term to en­ compass certain communications transmitted by “broad­ cast, cable, or satellite.” §434(f)(3)(A). When Congress was developing BCRA, the video-on-demand medium was still in its infancy, and legislators were focused on a very different sort of programming: short advertisements run on television or radio. See McConnell, 540 U. S., at 207. The sponsors of BCRA acknowledge that the FEC’s im­ plementing regulations do not clearly apply to video-on­ demand transmissions. See Brief for Senator John McCain et al. as Amici Curiae 17–19. In light of this ambiguity, the distinctive characteristics of video-on­ demand, and “[t]he elementary rule . . . that every reason­ able construction must be resorted to, in order to save a statute from unconstitutionality,” Hooper v. California, 155 U. S. 648, 657 (1895), the Court could have reasonably
