People v. Mbaabu, 213 Cal.App.4th 1139, 152 Cal.Rptr.3d 818, 821 (4th Dist.Feb. 14, 2013) (We hold that a motion to vacate the judgment in the nature of coram nobis is not a proper vehicle for relief from a constitutional violation of the defendant's right to effective assistance of counsel.). Further, even if defendant's motion was treated as a petition for writ of habeas corpus, it should have been denied as untimely and duplicative, in addition to lacking in any evidence from the defendant that he would have rejected the offer and gone to trial had he been properly advised of immigration consequences.
