Prosecutor on Willie Nelson's Side in Pot Bust?

The judge in Wilie's Texas marijuana case rejected a plea deal struck between Willie and the D.A. in which Willie would have paid $500 and the case would have gone away. The judge felt the deal reeked of celebrity justice so he told them to come up with a stronger punishment -- with a maximum of one year in jail.

But sources connected with the case tell TMZ ... there's a "strong possibility" the prosecutor will not recommend a stronger punishment, but instead just sit on the case until it's dismissed for lack of prosecution.
