Key legal question

Extracted holding
The use of LSE table T7S was lawful because it better reflected the insured person's remaining, realistic and familiar administrative work capacity and the factual prerequisites for that choice were not shown to be manifestly incorrect.
Extracted reasoning
She had long experience in commercial work, had performed bookkeeping tasks, and her work-training results supported such administrative helper work. Her lack of public-sector experience, age, and absence of formal qualification did not make the choice of T7S unlawful.
