SELF-SERVING EVIDENCE:

     Self-serving and unsubstantiated declarations are insufficient to establish a case before quasi-judicial bodies where the quantum of evidence required to establish a fact is substantial evidence. Often described as more than a mere scintilla,  substantial evidence is such relevant evidence as a reasonable mind might accept as adequate to support a conclusion, even if other equally reasonable minds might conceivably opine otherwise.
