As I have noted in the past, this requirement is a real, jurisdictional prerequisite to our exercise of review and should be treated as such. See People v. N.A.S. , 2014 CO 65, ¶¶ 60–67, 329 P.3d 285, 298–300 (Márquez, J., dissenting); People v. Thames , 2015 CO 18, ¶¶ 29–36, 344 P.3d 891, 899–900 (Márquez, J., dissenting).
