congress has a special concern for taxpayers who are seeking a refund of tax that they had her paid and that the language of the statute makes that clear it's undisputed that overpayment interest is not a ta much but it wasn't long sleeve collected on the other hand if the ire of course billy collects the correct amount of underpayment interest but not excessive but does so after the limitations period and collection has run that was not excessive it was the correct amount preserve that distinction between those two concepts critically bank of america thank you thank your honor i quickly bank of america has not alleged tha circuit explain this use of the present perfect tense the court got really into the grammar of the provision and the language of the statute indicates that the sums in the statute must have been excessive or wrong flick like that at some point in the past claims for tax refunds and the nd opinion of the supreme court on the floor of cases the court observed the provision of the keystone and a carefully articulated and quite complicated structure of tax laws and in our briefs we walk through several of differences so the text has been avoid the cost and inconvenience of litigating in d c there's no dispute the suits to recover taxes to recover penalties to recover a standalone underpayment interest even to recover overpayment wallace i have a few questions on page let's start with this on page fifty of the red great bank of america search that the two district courts that next question isn't the lack of additional analysis the problem with the district court decision below it's on appeal here i don't think that this court needs to pos closely the district court cases you have to so i i get your drift you're not trying to defend the opinion below let's let's move over to legislative history on page fifteen of the read brave b of a says that  stand alone over paying the interest cases but they on page thirty one dollars of the gray brief the government although they say legit street doesn't matter is that after the hearing the treasury department sent a letter to the on my line of questions here my government contends as i as i referenced we quote need not delve into the let history because the supreme court has held that as  simply have not alleged to have been excessive both the grammars awkward there but bank of america is not allege that those amounts have been excessive and just looking at the plain text of the statute those claims do not fall under  th circuit erred in the analyzing a paraphrase of the statute and looking at whether the government would retain access as some but that's not the language that congress wrote congress allows people to recover any sum alleged to have been  that the principles regarding interpret in a waiver of sovereign immunity are longstanding and really have not been questioned so if there is an ambiguity in the text and again we don't think there is but if there's an ambiguity supreme court upheld again and again but that must be interpreted in favor of immunity no bank of america does have a remedy here it could have brought one case in the court of federal claims for all of its interesting claims so we're not at all trying to focus close their opportunity to seek a remedy we just think that the right place to bring these overpayment interest claims is in the court of federal claims where bank of america already has an interest
