UNAT considered the Secretary-General’s appeal, specifically as to whether Mr Gehr was prejudiced or discommoded by the fact that his rebuttal was conducted by the rebuttal panel established in 2011. UNAT did not find that Mr Gehr’s obligation to engage with a panel established pursuant to ST/AI/2010/5 was, in and of itself, sufficient to merit an award of compensation, in the absence of specific harm or prejudice arising therefrom. UNAT held that the breach was not of sufficient seriousness to merit a compensatory award. UNAT allowed the appeal and vacated the UNDT judgment in its entirety.
