धर्मस्थः प्रदेष्टा वा हैरण्यदण्डमदण्ड्ये क्षिपति क्षेपद्विगुणमस्मै दण्डं कुर्यात् हीनातिरिक्ताष्टगुणं वा ॥ कZ_०४.९.१८ ॥
dharmasthaḥ pradeṣṭā vā hairaṇyadaṇḍamadaṇḍye kṣipati kṣepadviguṇamasmai daṇḍaṃ kuryāt hīnātiriktāṣṭaguṇaṃ vā
If a judge or an executive officer (pradeṣṭā) imposes a monetary fine on one who is not liable to be fined, he shall be punished with a fine double the amount wrongfully imposed; alternatively, where the amount is deficient or excessive, an eightfold penalty (relative to the shortfall/excess) shall be applied.
To make abuse of fining power unprofitable and risk-dominant, preventing fines from becoming a revenue-by-coercion tool.
