Norm Snedden opened a sole practice in February 1960, before forging a partnership with Allan Hall in October. Both formerly worked in the Crown Solicitor's Office. The firm (then named Snedden & Hall) was established in the same year that Canberra's population reached 50,000.

Norm and Allan were joined by John Gallop in January 1962 and the firm became known as Snedden Hall & Gallop. They were among only 23 solicitors in private practice in the ACT at that time.

The following year, Prime Minister Robert Menzies unveiled the Law Courts Building in Knowles Place adjacent to City Hill. The ACT Supreme Court commenced sitting in the new building in May 1963. Snedden Hall & Gallop was among the first firms to represent clients in the new courtrooms.

The Snedden Hall & Gallop "Downtowner" was a free bus service travelling around Canberra City in the early 1990s

With many government departments relocating to Canberra from Melbourne in the 1960s, the ACT grew rapidly and demand for legal services expanded. By the end of the decade, Snedden Hall & Gallop was a broad practice including business law, property transactions and all types of litigation.

Many of the region's most prominent legal practitioners have developed careers at Snedden Hall & Gallop. Over the years, some of our lawyers have gone on to hold the presidencies of  the ACT Law Society and ACT Bar Association and have become barristers, lecturers, commissioners and judges.
