After a recipient of advance notice responds to the advance notice of the person providing it by giving the person a written summary of the recipient's answers to the substance of the claim and essential points of dispute referred to in paragraph (3) of the preceding Article that the person has detailed in the written advance notice they have provided, the recipient, within four months after the day on which the advance notice was provided and before the action is filed, may specify a reasonable time frame for response and direct a written inquiry to the person providing advance notice, in order to elicit from that person a response in writing, or, at the option of the person providing the advance notice, in writing or by electronic or magnetic means, with regard to information that will clearly be necessary for preparing allegations or proof if the action is filed.
The provisions of the proviso to paragraph (1) as well as the provisions of paragraph (2) and paragraphs (4) through (6) of the preceding Article apply mutatis mutandis to a case as referred to in the preceding paragraph. In such a case, the term "written advance notice" in paragraph (4) of that Article is deemed to be replaced with "written response", and the term "advance notice by electronic or magnetic means" is deemed to be replaced with "response by electronic or magnetic means".
It is not permissible for an inquiry as referred to in paragraph (1) to be made based on a response to an advance notice that duplicates any previous advance notice.
