11.      (1) A person shall cease to be eligible for subsidiary protection when the circumstances which led to his or her eligibility for subsidiary protection have ceased to exist or have changed to such a degree that international protection is no longer required.

(2) In determining whether subsection (1) applies, regard shall be had to whether the change of circumstances is of such a significant and non-temporary nature that the person no longer faces a real risk of serious harm.

(3) Subsection (1) shall not apply to a person eligible for subsidiary protection who is able to invoke compelling reasons arising out of previous serious harm for refusing to avail himself or herself of the protection of his or her country of nationality or, being a stateless person, of the country of former habitual residence.
