Case Summary

This is an Employment Appeal Tribunal decision concerning case management errors in an employment tribunal. The appeal concerns whether the Employment Tribunal properly removed the July 2018 meeting issue from the list of issues and excluded parts of the claimant's reply witness statement. The EAT upheld the tribunal's case management decisions, finding no error in law.

The EAT found no error in law in the Employment Tribunal's case management decisions. The tribunal properly removed the July 2018 meeting issue because it predated the territorial jurisdiction date of 7 September 2017, and the tribunal properly excluded witness statement material that was repetitive or went beyond the agreed list of issues.

• •Whether the Employment Tribunal erred in law in removing an issue from the list of issues
• •Whether the Employment Tribunal erred in law in excluding parts of the claimant's reply witness statement
