LAWRENCE, Kan. (AP) — A Douglas County judge has ruled that a University of Kansas student who was expelled over tweets to an ex-girlfriend must be allowed to re-enroll. But Judge Robert Fairchild issued a stay of his ruling Monday to allow the university to appeal. The university says it expelled Navid Yeasin last November because he violated an order not to contact the ex-girlfriend by sending the tweets. Fairchild ruled in September that the university had not followed its own rules of student conduct because it did not show that Yeasin posted the tweets while he was on campus. The Lawrence Journal-World reports that Yeasin, a senior in petroleum engineering, said no other school in the state offers the program he needs to graduate and he does not want to pay out-of-state tuition.
