Shirleen Ong appears as counsel of record in 8 reported Malaysia judgments (2025–2026). These were heard before MYFC (6) and MYCOA (2).

On the court record

An appellate company-and-property litigation practice in the Federal Court and Court of Appeal.

Shirleen Ong appears at the appellate level, with the reported decisions divided between the Federal Court (Mahkamah Persekutuan) and the Court of Appeal (Mahkamah Rayuan), and weighted heavily toward the respondent side. The reported work is company and property litigation. A recurring matter concerns a corporate party as appellant and a dispute over the rights of purchasers — including a question about the position of the original purchasers of a development — so the practice engages both corporate rights and the entitlements of purchasers under a property transaction.

Appearing largely as respondent, the practice is instructed in defending appellate outcomes — resisting a corporate or purchaser appeal and holding the decision of the court below. The reported matters engage the provisions of the Companies Act governing corporate rights and the contractual and statutory framework that governs a sale of property and the position of successive purchasers, in disputes that turn on questions of law suitable for resolution in the highest courts.

The work turns on the construction of corporate and property instruments and on the statutory framework governing companies and sales of land. In the company matters the argument concerns the rights and obligations attaching to corporate ownership; in the purchaser matters the entitlements of the original and subsequent purchasers under the governing contract and statute. Because the matters sit in the Federal Court and Court of Appeal, the argument is confined to questions of law and the correct application of principle to the facts as found below.

The overall profile is an appellate company-and-property litigation practice in the two highest courts, weighted toward the respondent side. The matters turn on the Companies Act, the law governing sales of property and the position of purchasers, and the principles of appellate review, rather than on any criminal or public-law dimension, marking a practice concentrated on corporate and property rights at the appellate level.
