Some important points raised here, especially the right of an accused to know the charges and offer a defense, certainly before sentence is carried out. As an occasional browser of the C & A forum, I can see problems with the accuser not having filled out the form properly. Some tweaks may deal with both these problems.
First the form can include an requirement the accuser send the accused a copy of the charge, with exceptions allowed in certain circumstances, That notice could include the standard notice of the right to offer a defence. . If the notice to the accused has not been sent and the C & A folk feel it should be sent at this time, they can send a copy of the accusation to the accused with the opportunity to make a defense and this may resolve the matter without any need to go further- there is a reasonable explanation for the accused behavior. If they see some basis for an investigation, they can proceed to do that, with or without notification depending on the circumstances- say,there is a reference made to a Wall post, might be a good idea to check out what is there before it can be erased. Again it may be possible that a preliminary investigation , quick peak, shows the innocence of the accused or some way or resolving matters quickly and fairly.
BUT if a quick peak, a preliminary investigation, sees some merit in the accusation. then the C & A folk, again perhaps with some exceptions, can notify the accused of the charge and provide relevant details.: " From looking at game XXX and wall post YYY, ts seems the two of you may be conducting secret diplomacy, What do you have to say for yourselves?" There may be an explanation, or a guilty plea, But if the ccused denies the charge and the C & A folk don't buy the defense, they see something worth digging into deeper, then there can be a substantial digging into the case.
So apart from offering the accused some basic rights, notification of charges before sentence can save work.
Appreciate all the C&A folk have done, are doing and will do.
