This section applies where—
The directors of the company (except any without whose knowledge or consent the prospectus was issued) and any other person who authorised its issue are liable to indemnify the person named, or whose consent was required under section 61 (as the case may be), against all damages, costs and expenses to which he may be liable by reason of his name having been inserted in the prospectus or of the inclusion in it of a statement purporting to be made by him as an expert (as the case may be), or in defending himself against any action or legal proceedings brought against him in respect of it.
A person is not deemed for purposes of this section to have authorised the issue of a prospectus by reason only of his having given the consent required by section 61 to the inclusion of a statement purporting to be made by him as an expert.
