2009 April Fools Event

I'm taking my emeyloprs to a Tribunal and the disciplinary system is only really used by the management to settle personal scores. If everything disciplinary for like for like offences was harsh, that would be consistent and in it's own way, then fair enough.But if the offender is a management favourite they can be amazingly lenient for serious offences. They have given me some contradictory ones and are withholding others. How do I go about finding out information that they don't want me to know?Any good ideas please?
