[@Dirty Dan] in skyrim necromancy hasn't been outlawed, that was the mages guild that outlawed it. 
in the college of winterhold there was no such ban on the practise but it was genuinely frowned upon


[i]" College of Winterhold in Skyrim allows (to some degree) the practice of Necromancy, as many of the spells in the Conjuration field of magic are spells that reanimate fallen corpses. Skyrim as a whole technically permits the practice of necromancy, but the population is very disapproving of its practice and might even treat necromancers with hostility." [/i]


"As the College was independent from the Mages Guild, Necromancy was never made illegal by the College, unlike the Mages Guild in Cyrodiil. For the College of Winterhold, the practice was generally regarded as a tool, not a weapon, although practicing it outside of the College was advised against by Phinis Gestor. Like Cyrodiil, there were still wandering groups of Necromancers that did not function alongside the College. Since the College was independent of the jurisdiction of the Mages Guild, it was unaffected by the Necromancy Ban of 3E 431 and the subsequent eradication of that ban which led to battles against Mannimarco.!"
