Minn. Stat. § 15.415: CORRECTIONS IN TRANSACTIONS, WAIVER.

In any instance where a correction concerning any state department or agency transaction involves an amount less than the administrative cost of making the correction, the correction shall be waived unless it is possible at a relatively nominal expense to include the correction in a later transaction. If the amount of any correction is less than $5 it shall be prima facie evidence that the cost of the correction would exceed the amount involved.
