Allen Allen & Hemsley (AAH). This created one of the largest law firms in the Asia Pacific. The firms had been associated for 15 years prior to the merger through the Allens Arthur Robinson Group alliance. Allens dropped the "Arthur Robinson" part of its name on 1 May 2012. From that date, Allens began operating in an exclusive integrated alliance with the Magic Circle law firm Linklaters, each firm remaining financially independent. The firms operate two joint ventures in Asia. The firm has an arrangement with Widyawan & Partners for its Indonesian operations. Controversies In the early 1990s, a controversy arose when Adrian Powles, a former partner in the London office, was discovered to have secretly accessed a client's trust account to fund a gambling addiction. A Sydney journalist, Valerie Lawson, published a book in 1995 entitled The Allens Affair that details the Powles case and touches on much of the early history of the firm. Corporate art collection and involvement with the arts The firm has a large collection of Australian contemporary art. Included within its collection are works by Rosalie Gascoigne, David Aspden, Emily Kame Kngwarreye, Dale Frank and Ildiko Kovaks. There are over 1,500 works in its offices across Australia and Asia. The firm provides pro bono support to the Arts Law Centre of Australia, and is an ongoing patron. The firm acted on behalf of Angus & Robertson in an obscenity trial brought for selling Philip Roth's novel Portnoy's Complaint.
