What are some cases where a defendant has entered a plea to plead guilty to a charge of perverting the course of justice?

People v. Seeber , 4 N.Y.3d 780, 793 N.Y.S.2d 826, 826 N.E.2d 797 [2005] ); new evidence tending to prove innocence ( People v. Lewis , 13 A.D.3d 810, 788 N.Y.S.2d 181 [3d Dept. 2004] ); and ineffective assistance of counsel ( People v. Cepeda , 29 A.D.3d 491, 816 N.Y.S.2d 437 [1st Dept. 2006] ). A determination of whether the defendant has entered the plea voluntarily, knowingly and intelligently is left to the trial court's sound discretion ( People v. Nixon , 21 N.Y.2d 338, 355, 287 N.Y.S.2d 659, 234 N.E.2d 687 [1967] ).
