Uzodinma appoints retired justice nnadi the 28th adviser

I'm not aware of any information about Uzodinma appointing a retired Justice Nnadi as the 28th adviser. Can you please provide more context or clarify which Uzodinma you are referring to? Is it Hope Uzodinma, the Governor of Imo State in Nigeria? If so, I'd be happy to help you find more information about the appointment.
