Remove the cause and the effect will cease.

Explanation

(English-origin maxim.) Eliminating the cause of a legal obligation or wrong terminates its ongoing effects — this maxim supports actions to enjoin continuing harm at its source.

Where this applies

• A court issues an injunction shutting down a factory that is polluting a river, and the pollution downstream stops — remove the cause and the effect ceases.
• A landlord repairs a leaking roof that has been causing mold in the apartment, and the mold problem goes away.
• A school board fires a principal whose discriminatory policies were causing enrollment to drop — once the cause is removed, families begin returning.
