Vaisesika Sūtra 7.2.22

कारणपरत्वात् कारणापरत्वाच्च ॥२२॥

kāraṇa-paratvāt kāraṇa-aparatvāt ca ॥22॥

[कारण-परत्वात् (kāraṇa-paratvāt) - due to precedence in cause; कारण-अपरत्वात् (kāraṇa-aparatvāt) - due to subsequence in cause; च (ca) - and;]

Because cause could either be in precedence or could be in subsequence too.
