Most jurisprudence has nothing to say about informal relationships in courts. If mentioned at all, they are often singled out as peculiar pathologies of corrupt or autocratic regimes (usually in the East or South). This remarkably rich collection upends such easy forms of ignorance and simplification. It shows such relationships to be pervasive, multi-form, variable both in degree and kind, and very often central to the ways things work, both inside and outside the formal institutions of the law. Its contributions are scholarly, diverse, illuminating and – very often – astonishing in their range, variety and insights.
