Section 25

If any employer or person claiming compensation objects to any notice of assessment of compensation issued by the Commissioner under section 24(2), he shall, within a period of 14 days after the service of the notice of assessment (or such longer period as the Commissioner may, in his discretion, allow in any particular case), give notice of his objection in the prescribed form and manner to the Commissioner stating precisely the grounds of his objection.

The Commissioner shall disregard any ground of objection that is contained in any notice of objection given outside of the period allowed for objections under subsection (1).
