A former medical director at the Department of Health and Social Care was unfairly dismissed after raising concerns over the government's coronavirus response.
Dr Rosalind Ranson took an employment tribunal against the DHSC after her post wasn't transferred to Manx Care when it was set up in April last year.
The tribunal heard she warned a graph used by the government in press briefings underestimated the risks of the virus spreading and the effect of raising restrictions.
But that led to a row with Kathryn Magson, the DHSC's chief executive - she was criticised by the tribunal for not disclosing evidence.
The hearing found in favour of Dr Ranson, and there'll now be a hearing to decide how much the government should pay her.
