Let's discuss this without prejudice, calling a spade a spade.
公平無私 emphasizes impartiality and selflessness, while 是々非々 focuses on judging each matter on its own merits, right or wrong.
虚心坦懐 means being open-minded and free from preconceptions, whereas 是々非々 is more about making clear judgments of right and wrong.
A yojijukugo composed of 是 (right) and 非 (wrong) repeated, literally 'right-right wrong-wrong'. The exact historical origin is uncertain, but it reflects a classical Chinese-influenced expression for impartial judgment.
