Veil of Ignorance Rules in Constitutional Law

Adrian Vermeulet
A veil of ignorance rule (more briefly a veil rule) is a rule that
suppresses self-interested behavior on the part of decisionmakers; it does so
by subjecting the decisionmakers to uncertainty about the distribution of
benefits and burdens that will result from a decision.' A veil rule may
produce this distributive uncertainty by either of two methods. One method
is to place decisionmakers under a constraint of ignorance about their own
identities and attributes. John Rawls coined the phrase veil of ignorance
to describe a hypothetical original position in which principles of justice are
chosen under precisely this constraint.2 But that is a special case of veil
rules generally, indeed a radical case. Rawls's thought experiment
introduces uncertainty by allowing the decisionmaker to know the
distributive consequences of a decision on future citizens-call them A and
B-but denying the decisionmaker the knowledge of whether she herself
will occupy A's position or B's position. Where veil of ignorance rules
appear under historical rather than hypothetical conditions, however, the
relevant decisionmakers will usually know their own identities and
interests. Veil rules that appear in actual constitutions, then, more often
adopt a second method for introducing uncertainty: Although the
decisionmaker knows or can guess whether she will occupy A's or B's
position, the rule introduces uncertainty about whether A or B will reap the
greater gains from the decision.3

1. For a simple example, consider a rule that requires an official with regulatory authority
over the stock market to place her assets in a blind trust. Even if the official is self-interested,
she will be uncertain whether any given decision will increase or decrease the value of her
portfolio. She will thus be unable to skew her decisions in order to promote her personal interests.
Other homely examples are blind grading and the practice by which orchestras place auditioners
behind a screen.

3. An intermediate case occurs when a decisionmaker faces a decision that will principally
affect not the decisionmaker herself, but her (genetic) descendants. If the time horizon over which
the decision will matter is long enough, the attributes of descendants may be so difficult to predict
that the decisionmaker will effectively be left ignorant of the identity of the persons whose
interests she would favor, if she could. In this vein, participants at the Constitutional Convention
