Shujauddin Siddiqi was born in Delhi and carved out a playing career before moving into officiating. Between 1939 and 1946, he played seven Ranji Trophy matches for Delhi. As a leg spinner, he collected 12 wickets at an average of 28.75. With the bat, he scored 138 runs at an average of 12.54.
Following Indian independence, Siddiqi moved to Pakistan and continued his involvement in the sport as a first-class and Test cricket umpire. His officiating career included high-stakes domestic matches that tested his decision-making skills.
One such occasion occurred in March 1946 during the Ranji Trophy semi-final between Southern Punjab and Baroda. Siddiqi umpired the match, which lasted nearly four days and ended in a rare tie. After Southern Punjab posted scores of 167 and 146, and Baroda replied with 106 and 207, the teams remained deadlocked. Because the scores were tied, the match winner was decided by a coin toss rather than cricket performance.
