Kautilya's Arthashastra 7.8.9

7.8.9

tam itaras tadātve cāyatyāṃ ca kramam avekṣeta //

When a king means to harass the people of an enemy or to break the agreement of peace between a friend and a foe, or when he suspects of another's attack upon himself, and when owing to any of these causes, he wants to break peace with his ally, he may demand from the latter an enhanced amount of profit long before it is due. The latter under these circumstances may demand for a procedure (krama) either at the present or in the future. The same procedure explains the cases treated of before.
