Overview

• At the 2025 Championships, every line call is made by Hawk-Eye’s multi-camera electronic system with decisions final and no player challenges allowed.
• Calls of “out” and “fault” are voiced by pre-recorded All England Club staff, alternating male and female announcements to prevent confusion on adjacent courts.
• Wimbledon is monitoring audio levels and system performance throughout the tournament to ensure electronic calls remain audible and reliable.
• Approximately 300 human line judges were phased out, with around 80 retained as match assistants to support chair umpires and step in during rare technical issues.
• The switch follows full ELC adoption at the Australian Open in 2021 and the US Open in 2022 and was designed to enhance officiating accuracy rather than reduce costs.
