EMPLOYMENT TRIBUNALS (SCOTLAND) Case No: 4100710/2025 Held in Edinburgh on April 2026 Employment Judge M A Macleod Mrs M Boyle v Royal Mutual Insurance Society Ltd — 2026

The underlying proceedings began with Mrs Boyle's sex discrimination complaint, and an earlier amendment adding disability discrimination claims had been granted. The further amendment, initially submitted on 8 December 2025 and particularised on 16 January 2026, proposed allegations concerning discrimination arising from disability, reasonable adjustments, direct sex discrimination, victimisation, performance processes and grievance procedures.

Applying the amendment factors in Selkent Bus Co Ltd v Moore, the Tribunal found that the proposed amendment was relatively significant, introduced new facts, partly covered matters already pleaded and lacked specification and detail. The respondent did not contend that the new allegations were time-barred. Having considered the claimant's previous opportunities to amend, the work already undertaken to define the claims, the interests of both parties and the overriding objective, the Tribunal concluded that allowing another amendment would cause further delay and would be disproportionate. The amendment application was therefore refused.

The Tribunal also directed that case 4100710/2025 should not be combined with Mrs Boyle's separate claim, case 8000498/2026, because combination was likely to cause significant and unnecessary delay. The merits of the sex discrimination, disability discrimination and victimisation allegations were not determined, and the judgment records no monetary remedy.
