68V. Rectification of mistakes
With a view to rectifying any mistakes apparent from record, the competent authority or the Appellate Tribunal, as the case may be, may amend any order made by it within a period of one year from the date of the order:
Provided that if any such amendment is likely to affect any person prejudicially, it shall not be made without giving to such person a reasonable opportunity of being heard.
