After a cause of action has accrued on any obligation of a partnership, any act, admission or acknowledgment by any partner acting in the ordinary course of the business of the partnership or with the authority of his copartners which removes the bar of the statute of limitations or causes the statutes to begin running anew with respect to the partner doing such act or making such admission or acknowledgment has a like effect with respect to all of the partners and with respect to partnership liability, but when any partner is not so acting and does not have the authority of his copartners, any act, admission or acknowledgment by such partner which removes the bar of the statute of limitations or causes the statute to begin running anew has such effect only as to the partner doing such act or making such admission or acknowledgment, and shall not renew, extend or in any manner impose liability of any kind against any partner who has not authorized or ratified the same nor against the partnership.
