Narrative:

Maintenance control had signed the aircraft off for a one time ferry flight. The MEL item in question was captain's pitot heat inoperative. I reviewed the MEL which stated; no flight through known or forecast icing conditions. Also; flight must be conducted in day VMC only. I determined that due to the fact that it was evening civil twilight; that day VMC day operations could not take place. Also; due to the fact that cvg WX was 2000 ft overcast; light rain and br and deteriorating; that this flight would be in icing conditions. I conversed with maintenance control about my concern for safety. They told me because this is a ferry flight; the MEL could be disregarded. I was uneasy about this so I called union safety; which contacted the crj program manager; who also agreed with my concerns. The final outcome of this was that I refused the flight for concerns of safety of flight with an aircraft through icing conditions and at night; when the guidance of the MEL tells me it is not safe.
