The complaint should not have been allowed to proceed. Auda clearly gives an example which is exactly the same. Auda even found time to write a Poem in their blog about such complaints!
AUDA stuffed up by allowing the complaint to proceed and they need to stop allowing complaints such as these

"An important aspect of domain name registration is the upkeep of contact information – the most critical of these, is the registrant email address.
It is the method by which most domain name providers (registrars and resellers) attempt to contact registrants in order to send out renewal notices. Unfortunately, some registrants either forget, or neglect, to update their information once a change has occurred; and not all providers attempt to use alternate means to contact a registrant. As well, it is common practice for registrants to delegate responsibility for their domain name registration (in some cases without their knowledge or approval) to a third party to manage.
The loss of a domain name registration can have a significant impact on a registrant and
if the domain name is of a generic nature, it is more likely to be taken by someone else as soon as it becomes available. And it is not always likely that the previous registrant is able to recover their domain name in such situations.
So, to avoid the situation of finding out that your domain name has expired or, even worse, been purged and registered by someone else, be vigilant in maintaining your domain name registration. Whenever your details change, contact your registrar or reseller and inform them of that fact. And double-check that the update has been performed, otherwise the following poem may be what ends up happening to you:
From auDA’s ‘Woe Is The Integrity Of .au Contact Information’, 2011.
The quality of contact information should not be treated with disdain.
For your name may droppeth as the gentle rain from heaven
Into the droplist where the opportune may then be blest;
It curses him that is idle and blesseth him that is watchful.
Though a complaint be thy plea, consider this,
That, in the course of investigation, none of us
Will see the past and only consider the present;
Should the current holder be eligible, and
Refuse salvation: do pray for mercy;
Which if thou follow, the court of auDA policy,
Must give judgment against the complainant."
