There are repricussions for forcefully bonding a man. It's mentioned fairly regularly in the later books, although the two instances that I recall in the series were never brought up to anyone who could act to punish the sister who did it. In one case, even though it was done to save a life, was so unusual to begin with, wasn't revealed to the tower until near the end of the series. I'm not entirely sure that Ewaine (sp?) was ever totally sure of what happened.<br/><br/>In the second instance, the forceful bonding of Ran,she never returned to the tower and few knew about it who would be in a position to act because it would anger what they feared was an already mad Dragon.<br/><br/>It's not against Tower law, but it is against Tradition, which is as strong as, or stronger, than the actual law. Another tidbit repeated throughout the series in regards to tower law. Up until Ran's bonding, it hadn't happened in centuries because the tower considered it a form of rape.
