KENNEDY, J., concurring 

F. 3d  1142,  1149–1158  (CA10  2016)  (Gorsuch,  J.,  concur-
ring), it seems necessary and appropriate to reconsider, in
an  appropriate  case,  the  premises  that  underlie  Chevron 
and  how  courts  have  implemented  that  decision.    The 
proper  rules  for  interpreting  statutes  and  determining
agency jurisdiction and substantive agency powers should 
accord  with  constitutional  separation-of-powers  principles
and  the  function  and  province  of  the  Judiciary.  See,  e.g., 
Arlington, supra, at 312–316 (ROBERTS, C. J., dissenting).
