Michaela Tabb

In September 2015, appearing under her married name of McInnes, Tabb brought a court case in Bristol Employment Tribunal against World Snooker, claiming sex discrimination, unfair dismissal and breach of contract. World Snooker made an undisclosed out-of-court financial settlement, stating that "Michaela McInnes (Tabb) and World Snooker Limited have come to a confidential accommodation regarding the claims brought by Mrs McInnes in the employment tribunal." Since leaving the main professional circuit, Tabb has continued to referee Senior Tour events, including the World Seniors Championship final on 18 August 2019.

Her professional snooker refereeing career came to an end when she abruptly left the tour in March 2015. She subsequently brought a court case against the sport's governing body, alleging sex discrimination, unfair dismissal, and breach of contract. An out-of-court settlement was reached in September 2015, under which Tabb was paid an undisclosed sum.

On 19 March 2015, World Snooker announced that Tabb had left the professional refereeing circuit. The organization stated: "World Snooker would like to take the opportunity to thank Michaela for her contribution to World Snooker over the last 14 years, and wish her all the best with her future refereeing endeavours."

Tabb also refereed the 2012 World Championship final, in which Ronnie O'Sullivan defeated Ali Carter by 18 frames to 11 to win his fourth world title.

On the evening of 24 April 2012, during the first round of the championship, Tabb and female Chinese referee Zhu Ying simultaneously officiated on the Crucible's two tables. This marked the first time at the World Championship that two matches were simultaneously refereed by women. As the referees walked out to officiate, they were accompanied by the song "Sisters Are Doin' It for Themselves".

On 3 and 4 May 2009, Tabb became the first woman to referee a World Snooker Championship final, as John Higgins defeated Shaun Murphy 18–9 to capture his third world title. During the interval of the third session of the final, BBC2 broadcast a profile of Tabb, in which she discussed the pressures of juggling her family life with her busy refereeing and travel schedule.

On 18 February 2007, Tabb became the first woman to officiate at a world-ranking snooker final as Neil Robertson defeated Andrew Higginson 9–8 in the Welsh Open. On 20 January 2008, she refereed her first Masters final at Wembley Arena in London, in which Mark Selby defeated Stephen Lee 10–3. On 5 April 2009, she took charge of the China Open final in Beijing, where Peter Ebdon beat John Higgins 10–8.

In July 2003, dwindling sponsorship revenue forced the WPBSA to cut its number of tournament referees from ten to eight. Tabb's contract, along with that of Dutch referee Johan Oomen, was terminated on a last in, first out basis, threatening her future in the sport. However, the WPBSA soon reversed its decision to dismiss Tabb and she signed a new contract in September 2003.

On 23 January 2002, she became the first woman ever to referee at a professional ranking snooker tournament when she took charge of a first-round match between Ken Doherty and James Wattana at the Welsh Open in Newport. On 19 April 2003, she made her World Snooker Championship debut at the Crucible Theatre in Sheffield, refereeing a first-round match between Mark King and Drew Henry.

Stating that he wanted to change the dowdy, all-male image of snooker referees, Jim McKenzie, then chief executive of the World Professional Billiards and Snooker Association, recruited Tabb to the sport in 2001. Exempted from the customary five-year refereeing apprenticeship and placed on a fast-track toward officiating at professional ranking tournaments, she qualified as a Class 3 snooker referee in September 2001. She conceded that this fast-tracking generated resentment among her fellow officials and referees.

She began refereeing professionally on the pool circuit in 1997, and has officiated at top pool tournaments such as the WPA World Nine-ball Championship and the Mosconi Cup. After qualifying in 2001 to referee on the professional snooker tour, she went on to become the sport's highest profile female referee. During her 14 years on the tour, she became the first woman to officiate at a professional ranking snooker tournament (2002), the first woman to referee a ranking tournament final (2007), and the only woman ever to have refereed the World Snooker Championship final (2009 and 2012).

As an individual competitor, Tabb won the UK women's singles title in 1997. The following year, she won the European Women's Pool Championship in Gibraltar.

She made her professional refereeing debut at the St. Andrew's Cup nine-ball pool tournament in September 1997. She refereed on television for the first time the following year, when the 1998 St. Andrew's Cup, sponsored by Barry Hearn's Matchroom Sport, was broadcast on Sky. She went on to become one of pool's top officials; she has refereed at the WPA World Nine-ball Championship, the Mosconi Cup, and the sport's other premiere events. In 2017 Tabb became the head referee on the World Pool Series.

Tabb started playing competitive pool in 1991, at the age of 23. Selected the following year to play on the Scottish Ladies' Pool Team, she went on to captain the team to two consecutive "Grand Slams" in 1997 and 1998 by winning the Nations Cup, European Championships, and World Championships in the same season. She remained on the team until 2003. Her sister Juliette Tabb also played on the Scottish ladies' team between 1996 and 2008.

Tabb became involved in pool refereeing in the mid-1990s when she and her husband, professional pool player Ross McInnes, began running amateur eight-ball and nine-ball pool tournaments. McInnes subsequently encouraged her to pursue refereeing at a professional level.

Michaela Tabb (born 11 December 1967, in Bath, England) is a Scottish snooker and pool referee, notable for establishing significant milestones for women officials in professional snooker.
