Jerry Walter, head of corporate at Simmons & Simmons, acted for the club of which he is a member - the Marylebone Cricket Club (MCC) - when it ended a 211-year-old tradition on 28 September and voted to admit women to the club.
A special general meeting was held at Lord's cricket ground, which recorded a majority of almost 70 per cent in favour of admitting women for the first time, exceeding the two-thirds majority needed to change MCC rules.
Simmons & Simmons has been advising the MCC since 1987, and also advised the club on the two previous occasions when the vote came up - in 1992 and February 1998.
The advice covered ensuring that the rules regarding the vote and convening the meeting were being complied with in all respects by the MCC, and advising the committee on the conduct of the meetings. Walters said that "the analogy is with a public company which has high-profile issues raised at an extraordinary general meeting".
Walter was assisted by senior assistant Chris Hilditch who, like Walter, is a self-confessed cricket fan. Walter declined to say which way he voted but he said he was "supportive of the committee" in its attempt to open the club to women.
The firm also acts for the Williams and Red Arrows Grand Prix teams, as well as football club, Sheffield Wednesday.
