If you were rejected after passing the medical one or a combination of 3 things happened. 1st: if you were borderline on day 3 (panel and group interview/excercise) they send you to the medical then they compare notes at a later date and see if the "notes" are something they can live with, the actual decision is made higher up. 2nd: ties into the 1st but has to do with the psychologist meeting/interview, their notes are also compared with the panel's and again if there's something's they both have picked up on then that's it. Lastly, as mentioned earlier is the references and since you get to pick them they better be good.
