An interruption of service for more than 48 hours shall be reported to the Commission with a statement of the cause of interruption and its probable duration. Suspension of service for 5 consecutive days without notice to the Commission will be deemed sufficient cause for revocation or cancellation of the rights of the carrier, except if the suspension is caused by strike or labor difficulties, riot, insurrection, war, government decrees or an act of God. An order of revocation will not issue until the carrier is given opportunity for a public hearing on a complaint as to why the rights should not be revoked and cancelled.
