This act fits the definition of 'Mischief' under Section 425 of the IPC. The essential ingredients of mischief are: (1) intending to cause, or knowing that one is likely to cause, wrongful loss or damage to the public or any person; (2) causing the destruction of any property, or any such change in any property that diminishes its value or utility. By causing cattle to enter and damage Z's crop, A has intentionally caused a change that diminishes the crop's value, resulting in wrongful loss to Z. This is a classic example of mischief. It is not criminal trespass, as trespass requires the entry of a person, not an animal.
