I have noticed, in Qld at least, an increase in successful claims in QCAT for costs based on the characterization of the applicant (generally an owner) by the respondent (generally the body corp or committee – who often use the services of a lawyer) as being a vexatious litigant, or of the claims being frivolous.
I have found this to be a harsh and intimidating way of dealing with a frustrated owner (applicant) who has problems that are often genuinely concerning.
Although the use of the Tribunals is supposed to be a way of reducing costs it seems that those with the deepest pockets have the advantages.
