Although the Fourth Department affirmed defendant’s conviction, the court agreed with the defendant that the People improperly conditioned co-defendant’s plea upon his promise not to testify at defendant’s trial and threatened to increase the co-defendant’s sentence if he did testify.  The trial court eliminated the problem by permitting the co-defendant to testify without exposure to a more severe sentence:

We agree with defendant that it was improper for the People to condition the plea of a codefendant upon his promise not to testify at defendant’s trial and to threaten to increase the codefendant’s sentence should he violate that condition ….. As the United States Supreme Court wrote in Washington v Texas (388 US 14, 19), “[t]he right to offer the testimony of witnesses, and to compel their attendance, if necessary, is in plain terms the right to present a defense, the right to present the defendant’s version of the facts as well as the prosecution’s to the jury so it may decide where the truth lies. Just as an accused has the right to confront the prosecution’s witnesses for the purpose of challenging their testimony, he [or she] has the right to present his [or her] own witnesses to establish a defense. This right is a fundamental element of due process of law.” Thus, “substantial interference by the State with a defense witness’ free and unhampered choice to testify violates due process as surely as does a willful withholding of evidence” … . Here, however, defendant was not prejudiced by the improper plea condition inasmuch as the court granted his motion to permit the codefendant to testify on defendant’s behalf without exposure to a more severe sentence, and the court advised the codefendant of its ruling …. . People v Whitfield, 99, 4th Dept 3-21-14
