Humility holds a modest but important place among the judicial virtues. But in spite of its growing popularity, it does not yet have a place on the ‘central judicial virtues’ lists. This paper provides an argument that judicial humility, especially institutional judicial humility, should be considered a necessary judicial virtue at least in common-law jurisdictions. This is because it is a necessary ingredient in precedent-based decisions that are fully justified from the point of view of the law and of political (...) morality. Further, while it is sufficient that individual judges make decisions that a humble judge would have made, the judicial community must in fact be humble in order to produce fully justified common-law decisions – humility is therefore necessary as a community-virtue.
