A change of legal interpretation or administrative ruling
may be the result of a change in a regulation, a decision of the
United States Supreme Court, a Federal court order in a class action
case, or the issuance of an SSR or an Acquiescence Ruling.
A change of legal interpretation or administrative ruling
is not “good cause” to reopen a determination or decision
under the 2 or 4 year rules. Although a change of legal interpretation
or administrative ruling may be a basis for reopening within 12
months of the date of the notice of the initial determination, reopening
is appropriate only if the result would be more favorable to the
claimant.
