Slater and Gordon is a multinational law firm headquartered in Australia employing over 2,500 people worldwide. In 2007, Slater and Gordon became the first law firm in the world to go public. The firm is Australia's largest consumer law firm by total revenue. In 2012, Slater and Gordon entered the UK market with the acquisition of several UK based law firms, and has since become one of the UK's largest consumer law firms. In 2014 the firm was ranked as the 7th largest international law firm operating in the UK by revenue. In 2014, the firm's UK revenue exceeded £100 million for the first time, with a reported 119% increase on the previous year's turnover. The firm was founded in Melbourne, Victoria in 1935 by a barrister and solicitor from Irymple, Victoria, Hugh Lyons Gordon, and Labor politician Bill Slater.
On 20 March 2015, Slater & Gordon announced the acquisition of the professional services division of Quindell for £637m. The acquisition of Quindell’s professional services division was said to increase its market share of UK personal injury law to about 12 percent from the current 5 percent, making the firm the largest law firm in the country with respect to personal injury. The deal was, however, highly controversial, Quindell being seen as a "basket case" at the time, and many commentators questioned the wisdom of the acquisition, and the price paid.
