Narrative:

During preflight planning of the flight plan and the maintenance log; the first officer and I determined that with the combination of aircraft systems inoperative; complex MEL requirements; fatigue (third flight of the duty period and the late hour of the day); departure; enroute and destination weather and forecast; that it was not safe to continue to operate with this plan and this aircraft. Initially this was met with complete professionalism and concurrence as the PIC had made a final decision. I was then approached by line maintenance requesting my explanation for the aircraft refusal and their reiterating of the MEL and that it was legal to fly. This was followed by customer service reminding me that the flight was sold out and all of these people needing to get to their destination. As professional pilots; we always understand the desire for everyone to want to get where they are going and the need for the company to operate all scheduled flights. I am required and expected to make sound decisions based on my three decades of experience to maintain a safe operation. It is a responsibility I enjoy and; at the same time; take very seriously. This was a clear instance of pilot pushing by various entities and contrary to the core of [our company's] operating parameters.
