Sure the judge can reject the plea bargain, but if he does that he also has to reject the guilty plea that came with it and go to a jury trial. From all indications the judge was going to toss the deal out the window but retain the guilty plea and impose a heavier sentence. No one can say what the result of a trial would have been because there was no trial and it's pretty much impossible to hold a trial today on events that happened so long ago. If they even tried to do that, the victim would most likely refuse to testify and the charges would go out the window. The whole thing is one big cluster fuck because from the judge and prosecutor to Polanski himself, everyone screwed up.
And Doc, Lesley Van Houten should die in jail because she should have been executed in the first place along with all the other Manson family members.

No, that is not true. A judge can accept the guilty plea and at sentencing sentence within the guidelines of the law. There is nothing binding with a plea agreement. Once you plead guilty you cannot go back on it because a Judge rejects the sentencing recommendations from the prosecutor.
When you plea guilty to a crime, you are admitting that you have done the crime. A Judge will have you admit to the crime and in effect you are giving a confession in court which is admissible as evidence.
Most Judges will honor the plea agreement. In Polanski case, Polanski would have only pled guilty to the lesser offenses anyhow. The Judge has the option of rejecting the plea and the lesser charges per the plea agreement and forcing it to trial if he thinks that the evidence submitted in the indictment was too strong, or he could give the defendant the most stringent sentence under law, far greater than the plea agreement with the prosecutor.
When you take a plea agreement, you always take a gamble with the sentence.
You do have the right to appeal a sentence if the sentence given by the Judge is too harsh.
A good example of a plea gone wrong is the Jonathan Pollard case. Pollard plea was for spying for an ally, which is not espinoge. The agreement with the prosecutors was a sentence of 4 to 7 years. The Judge turned around and gave him Life in Prison. He has been in Max. Security for 23 years. In Pollard's case, while in prison awating sentencing, Pollard gave an interview to the media which was against his plea agreement. He received the maximum sentence for his admitted charge.
