पूर्वविप्रतिषेध conflict of two rules where the preceding rule super-
sedes the latter rule, as the arrival at the correct form requires it. Generally the dictum is that a subsequent rule should supersede the preceding one; cf विप्रतिषेधे परं कार्यम् P. I. 4. 2; but sometimes the previous rule has to supersede the subsequent one in spite of the dictum विप्रतिषेधे परम्. The author of the Mahabhasya has brought these cases of the पूर्वविप्रतिषेध, which are, in fact, numerous, under the rule विप्रतिषेधे परं कार्यम् by taking the word पर in the sense of इष्ट 'what is de- sired '?; cf. इष्टवाची परशब्दः । विप्रतिषेधे परं यदिष्टं तद्भवतीति l M.

Bh, Ahnika 1, पूर्वसूत्रे गोत्रस्य वृद्धमिति संज्ञा क्रियते M. Bh on I. 2.68; cf. also M.Bh. on P.IV.1.14 Vart. 3, VI.I. 163 Vart. 1, VII.1.18, VIII. 4.7.
