179.Section 45 provides that no decision of the First-tier or Upper Tribunal may be reviewed on more than one occasion. A decision on review to set aside an earlier decision and a re-made decision are, however, to be regarded as separate decisions from the earlier decision which was subjected to review and can, therefore, be the subject of a further review. Subsection (3) provides that the power of the Scottish Tribunals to review their own decisions does not affect their powers to correct minor or accidental errors in a decision administratively.
