(b) the dispute was referred to an adjudication officer or, as the case may be, the Court within the period referred to in paragraph (a).

(2) Notwithstanding subsection (1), an adjudication officer or, as the case may be, the Court may extend the period referred to in that subsection by a further period not exceeding 6 months where the adjudication officer or the Court is satisfied that the failure to refer the dispute within the period referred to in subsection (1) was due to reasonable cause.
