I think there are valid legally justifiable reasons for refusing the bounty, however they are outweighed by the reason for the bounty system to exist in the first place. Not paying someone over minor violations that they only did to get your attention to the fact that something was definitely important to you is not good practice when running a bounty for bugs.
