Entire fairness is the opposite pole from the business judgment rule. Where the business judgment rule presumes directors acted properly, entire fairness presumes nothing and puts the burden squarely on the defendant fiduciaries to prove the challenged transaction was fair in every respect. Courts break the inquiry into two strands: fair dealing, which looks at the process — timing, negotiation, disclosure, and how approval was obtained — and fair price, which looks at the economic and financial terms actually delivered to shareholders.

Entire fairness applies whenever the ordinary presumption of sound board judgment does not hold, most commonly in freeze-out mergers, other transactions with a controlling shareholder on both sides, or any deal where a majority of the deciding directors had a personal financial stake. A board can sometimes shift the burden back to the plaintiff by using cleansing devices — an independent special committee and an informed, uncoerced vote of disinterested shareholders — but even then the underlying facts about dealing and price remain central to the case.

Because fair dealing and fair price are each built from many small, contestable facts rather than one number, they are well suited to being modeled as separate dials rather than a single win probability. Juricratic lets a user weight process evidence and valuation evidence independently and see how each moves projected exposure, rather than collapsing a fairness fight into one undifferentiated 'strength of the case' figure.

Entire fairness review is the standard defense counsel most wants to avoid and plaintiff counsel most wants to trigger, because it flips the burden of proof onto the defendants. It governs the litigation strategy around controller transactions and freeze-out mergers from the earliest stages — parties often structure the deal itself around an independent committee and a majority-of-the-minority vote specifically to try to avoid, or survive, entire fairness scrutiny.
