This newsletter is about the important subject of invalidity, at the example of a recent judgment of the Court of Justice which confirms that the term invalidity in the context of the entitlement of staff to an invalidity allowance can only be interpreted as an incapacity to fulfil the duties within the own institution. If found invalid there, the staff member cannot be referred to the general labour market with the argument that he/she would be “not invalid” outside the institution. In other words, an invalidity allowance has to be granted independent of the capacity of the staff member to perform work on the general labour market.
