In 2019 Perrella Legal set a new benchmark for criminal defence practice in Western Australia, becoming the first specialist criminal law firm to achieve Quality Practice Standard (QPS) accreditation from the Law Society of Western Australia.
The QPS is awarded to firms that demonstrate exceptional operational excellence, underpinned by sophisticated, documented systems designed to enhance client outcomes and eliminate inefficiencies.
Achieving this accreditation requires the development and implementation of rigorous, tailored policies and procedures that exceed legislative requirements. Maintaining QPS status demands ongoing excellence, with firms subject to comprehensive annual independent audits and formal re-accreditation by the Law Society.
In a market of approximately 450 law firms across Western Australia, only 42 hold QPS accreditation—and only a small number of those operate as specialist criminal law firms.
As the first specialist criminal law firm to attain QPS accreditation, Perrella Legal stands at the forefront of quality, setting a standard of practice to which others aspire.
