Featured experience

Challenging local authority decisions

Challenging various local authority decisions to name particular schools in pupils’ Education, Health and Care Plans and lodging complaints with the Secretary of State for Education about the local authorities’ unreasonable actions in failing to apply the correct legislation or take into account the detailed consultation responses put forward by the schools. 

Disability discrimination claim

Successfully defending a disability discrimination claim against the school who were alleged to have indirectly discriminated against a pupil and failed to make reasonable adjustments by issuing a fixed term exclusion. The Tribunal agreed that although the exclusion amounted to unfavourable treatment linked to a disability, it was a proportionate sanction and justified to ensure the health and safety of staff at the school. The claim was therefore dismissed in its entirety. 

Disability discrimination claims

Successfully advising three separate schools faced with disability discrimination claims and bringing these to a conclusion without needing to expend time and costs in going to Tribunal. 

Exclusions support

Developing a comprehensive exclusions support pack of template letters, scripts, checklists, reports and FAQs for schools and trusts to use to ensure that any suspensions or exclusions are lawful, reasonable and procedurally fair. The pack is designed to ensure consistency, instill confidence and save costs.
