In Pawlak, TC Memo 1995-7, 69 TCM 1603 (January 10, 1995), the court observed that the employer/petitioner had (emphasis added):
QUOTE
"failed to prove its reasonable reliance on Corbel. Petitioner asserts
that at all times it relied on Corbel to ensure the Plans' compliance with
the law. The record does not contain any evidence supporting this
assertion other than statements made by Pawlak on behalf of petitioner.
Even if petitioner could demonstrate reliance on Corbel, our prior
opinions indicate that we will not excuse an employer's failure to
maintain a plan's qualified status because of reliance on others."
In Stark Truss Company, Inc., TC Memo 1991-329, 62 TCM 169 (July 17, 1991), the employer tried to argue that the IRS should cut it some slack on missed amendments because the employer had switched to a less experienced lawyer. That argument failed.
