I'm not sure about other places, but the Education Code in Texas has a line in it that 'no one is allowed to interfere with the education of another', or something along those lines. I don't remember exactly how it is phrased, but it means that no student, or adult, has the right by THEIR actions to make it difficult for someone else to learn. This covers disruptions in the classroom as well as things that happen outside the classroom.

Tell the principal that you do not want the boy near your children, and they should never be in the same class together. The boy has a history of bullying and they are allowing the bullying atmosphere to continue and are now contributors to any future problems. If you tell the principal this he will know they will be held liable for any future actions of the student. A lawyer might be needed.

Also point out the unevenness of punishment, such as your son genuinely tripping and then getting into more trouble than the bully who deliberately does things.

You might also insist on a meeting that includes both parents of the bully and the principal. Lay your cards on the table and let them know that from here on out there can be no 'sticking your head in the sand' about this boy's actions, as everyone has been informed, and that you are holding the adults responsible for any future aggression by the student. Criminal charges could be filed in the future if the parents continue to ignore their evil spawns actions, but a paper trail must back up the claim that the parents knew and did nothing.

added: my son faced bullies, too, when he was young. He was so big, though, that sometimes they claimed that Jeff was doing the bullying. That never lasted long upon observation. He was such a sweet child he wouldn't retaliate even when hit and kicked, because he was afraid of hurting anyone. He did, however, take my advice once and punched a kid in the nose, hard, because the kid hit him. This was in junior high and the kid never tried to hurt him again. He (bully) also realized to not mess with the center of the football team because he was the quarterback and my son would give him the ball and step aside for the defense to sack him, if the ticked Jeff off too much. It's called a 'look-out' block, where the lineman yells "look out" and steps aside. LOL
