Whose is the advantage, his also should be the disadvantage.

Explanation

(English-origin maxim.) He who enjoys the benefit must also bear the burden — cite this to prevent a party from claiming the advantages of a transaction while disclaiming its corresponding obligations.

Where this applies

• A company enjoys the tax benefits of a government incentive program but refuses to comply with the program's employment requirements; the court holds that whoever takes the advantage must also bear the associated burden.
• A landowner benefits from a public drainage system that protects his property from flooding but refuses to pay the assessment; the court rules he must bear the cost because the advantage and disadvantage go together.
• A partner takes a disproportionate share of profits but tries to avoid contributing to losses; the court holds that whoever enjoys the advantage must also accept the disadvantage.
