The problem is that members are only members in order to comply with the law. If and when the "bad members" are actually bad or simply pains in the ass is sufficient to deny them compliance with the AVIATION law then the door is open to vindictive, unsubstantiated behaviour to enable the expulsion of a member.
It is a different matter if the issue is NOT aviation related, but in an organisation in which members have consistently displayed their apathy it is hard to see how a "bad member" situation could arise. When does open discourse about the management or other get to the situation where "the organisation has been brought into disrepute" for example? In-fighting in this type of organisation is part of the internal politics.
If the so called "bad member"'s behaviour is aviation related it should be CASA who removes his flying privileges, not a private organisation who is concerned about its reputation. Having lost those privileges, continued membership will probably no be an option for the member as there is no reason to be a member.
In any event, the disciplinary document, seeks to deny human rights such as the right to silence, and consequently the rule against self incrimination. These rules apply to civil as well as criminal arenas. CASA should refuse to approve the document whilst the offensive policies form part of the document.
