'Other improper conduct' in s 38(2) of the Limitation Act 2005 (WA) bears its ordinary meaning of conduct not in accordance with propriety, and does not require moral turpitude akin to fraud. The impropriety must relate to the purpose or tendency of the conduct to deprive a prospective plaintiff of the reasonable opportunity to commence proceedings within the limitation period. A breach of contract, duty of care or fiduciary duty is neither necessary nor sufficient. The question is evaluative and attracts the correctness standard of appellate review.
