In 2002, top-flight British law firm Freshfields Bruckhaus Deringer helped get Trinidad and Tobago-born businessman Krishna Maharaj, who had been convicted of double murder, off death row in Florida. The firm represented Maharaj for free until 2008 when it applied, unsuccessfully, to get him out of jail.
This firm is typical of the trend.
At the world's biggest commercial law firms, who can charge US$800 an hour for their services, such noble efforts, known as pro bono publico in the Latin tongue that lawyers favour, are commonplace.
The American Bar Association calls the work of providing free legal advice a 'moral duty'.
But in Hong Kong, it seems, commercial lawyers are doing far from enough.
The South China Morning Post surveyed the world's 25 largest solicitors' firms, as ranked by The Lawyer magazine in 2006, about their pro bono efforts in Hong Kong.
Those who responded said uniformly they were helping charities with commercial law. Several firms are also assisting Filipino domestic helpers with employment disputes and helping refugees seek asylum through a voluntary organisation, the Hong Kong Refugee Advice Centre.
