The judge does not have to allow him to withdraw, it depends on whether he believes there is “good reason.” If he believes that the prosecution changed the agreement, that could constitute good reason. But it’s not a given.

Former national security adviser Michael Flynn filed a court motion Tuesday seeking to withdraw his guilty plea in a case that originated with the special counsel’s investigation.
Flynn’s legal team accused prosecutors of acting in “bad faith” and out of “vindictiveness” when they recommended in a court filing on Jan. 7 that Flynn receive up to six months in prison in his case.
Flynn pleaded guilty on Dec. 1, 2017 to making false statements during a Jan. 24, 2017 meeting with FBI agents regarding his interactions with Sergey Kislyak, who served at the time as Russia’s ambassador to the U.S.
