Clause 12

This Act shall apply to arbitral proceedings commenced on or after the date of commencement of this Act but the parties may in writing agree that this Act shall apply to arbitral proceedings commenced before that date.

Notwithstanding subsection (1), where the arbitral proceedings were commenced before the date of commencement of this Act, the law governing the arbitration agreement and the arbitration shall be the law which would have applied if this Act had not been enacted.

For the purposes of this section, arbitral proceedings are to be taken as having commenced on the date of the receipt by the respondent of a request for the dispute to be referred to arbitration, or where the parties have agreed in writing that any other date is to be taken as the date of commencement of the arbitral proceedings, then on that date.
