(1) A service provider is not capable of being guilty of an offence under section 49, so far as it relates to a publication that includes matter in contravention of a direction under section 45A(2), in respect of anything done in the course of providing so much of an information society service as consists in the storage of information provided by a recipient of the service if sub-paragraph (2) or (3) is satisfied. (2) This sub-paragraph is satisfied if the service provider had no actual knowledge when the information was provided that it consisted of or included matter whose inclusion in a publication is prohibited by a direction under section 45A(2). (3) This sub-paragraph is satisfied if, on obtaining such knowledge, the service provider expeditiously removed the information or disabled access to it. (4) Sub-paragraph (1) does not apply if the recipient of the service is acting under the authority or control of the service provider.
