Retrospective correction of registration certificate rejected after long acquiescence; amendment permitted only prospectively.

Retrospective correction of a registration certificate to include the oil-seed activity from 1951 was refused because the appellants had accepted and acted on the certificate as issued for about 23 years without challenge. That long acquiescence made the belated attempt to reopen the omission inconsistent and barred retrospective alteration of the record. The correction, if any, could operate only prospectively.

Issues: Whether the appellants were entitled to have their registration certificate corrected retrospectively so as to include the oil-seed activity from 1951.

Analysis: The appellants had accepted the registration certificate as issued and acted upon it for about 23 years without challenging the omission. Their belated request for retrospective correction was inconsistent with that long course of conduct, and the prior non-inclusion could not be reopened after such delay.

Conclusion: The claim for retrospective correction was rejected and the correction could operate only prospectively.
