This section applies where this Act provides for it to apply for the purposes of a provision of this Act (a "relevant provision").
In this section—
Day A is the day on which the complainant concerned complies with the requirement in subsection (1) of section 18A of the Employment Tribunals Act 1996 (requirement to contact ACAS before instituting proceedings) in relation to the matter in respect of which the proceedings are brought, and
Day B is the day on which the complainant concerned receives or, if earlier, is treated as receiving (by virtue of regulations made under subsection (11) of that section) the certificate issued under subsection (4) of that section.
In working out when a time limit set by a relevant provision expires the period beginning with the day after Day A and ending with Day B is not to be counted.
If a time limit set by a relevant provision would (if not extended by this subsection) expire during the period beginning with Day A and ending one month after Day B, the time limit expires instead at the end of that period.
Where an employment tribunal has power under this Act to extend a time limit set by a relevant provision, the power is exercisable in relation to the time limit as extended by this section.
