If ever you have read some gambling news today, an Italian Chair Umpire Francesco Totaro was suspended by ITIA Provisionally for grounds of match-fixing.[1]
“The International Tennis Integrity Agency (ITIA) today confirms that Italian chair umpire Francesco Totaro has been provisionally suspended from the sport, pending the full consideration of match-fixing charges.”
It looks like this isn't the first time that ITIA banned umpires due to match-fixing.
Umpires that is banned with the same offense of match-fixing
Majd Affi, a green badge chair umpire for 20 years
Abderahim Gharsallah, a white badge chair umpire
Mohamed Ghassen Snene, a green badge chair umpire
The latter two bans came from manipulating scores inputted into their electronic scoring devices, which did not reflect the actual scores on the court, it happens in Tunisia way back 2020.
Match fixing may not be discovered during the event but post reviews and appeals may open a panel for an investigation to determine if a match-fixing happens during the match.
