Removal of obstructions19

If any obstruction is caused to the operation of the opening mechanism of the bridge by any object left on the bridge or within the limits of deviation, the person in charge of the object shall remove it forthwith; and if he fails to do so the Council may take all reasonable steps to remove the obstruction and may recover the expenses reasonably incurred in doing so from–

a

any person by whom the object was put or left so as to become an obstruction to the operation of the bridge, or

b

any person who was the owner of the object at that time unless he shows that he was not, at that time, concerned in or aware of the object being so put or left.
