Section III : On means of injuring the enemy - Art. 24.
Art. 24. At the close of the war, the belligerent States shall do their utmost to remove the mines that they have laid, each one its own.
As regards the anchored automatic contact mines laid by one of the belligerents off the coast of the other, their position must be notified to the other party by the State that has laid them, and each State must proceed, with the least possible delay, to remove the mines in its own waters.
Belligerent States upon whom rests the obligation of removing these mines after the war is over shall, with as little delay as possible, make known the fact that, so far as is possible, the mines have been removed.
