we will start with the united states versus mell personal jurisdiction under code section twenty six of the seven hundred twenty six u s c seventy six of three subject matter jurisdiction under seventy six zero four and also to enforce the summons whether or not the powell test which is the administrative steps required by the code were taken prior to the enforcement summons we believe that the record below establishes a not of a factual dispute as to the issue of whether or not mr mellon's last unusual place of abode was fifth avenue in new york city that there should have been an evidentiary hearing required by united states  procedure that i've always followed is we call the judge's chambers and and ascertain whether or not we're going to have witnesses on the date of the return date of the order to show cause the judges will tell you yes you have bring your witnesses that day or no we'll have an oral argument and then we'll schedule the witnesses another debt so that has always been the procedure in summons and foursomes because it's very declaration supporting evidence the you believe supporting your that there was to meet the clark standard that you don't some unseen force mintz are summary proceedings you don't automatically get an evidentiary here you have to establish meaning the the person opposing the summons has to establish a factual dispute that that would overcome the presumption of regularity that comes with the i r s agents affidavit usually those factual disputes focus on the legitimate purpose but here the factual dispute went to the threshold matter whether or not the agency had jurisdiction did they they did they complied with seventy six all three is he conflated an internal revenue service summons with a grand jury subpoena so the you didn't understand that there's two levels of inquiry here first did the agency acquire jurisdiction over the witness second did the district court then have jurisdiction to resolve the dispute between the agencies and the witness which are two you know very different threshold following things i mean this is not a grand jury subpoena issued by the court itself the united states is an agency of the united states government the this is the agency has the power to do investigations under seventy six some two or that is what happened here they started an investigation in two thousand and twelve based on a confidential informant they the investigation was secret until such time that the government issued third party summonses background the critical question unusual place of abode and what do you say what do you identify as the error in the conclusion that an apartment that you don't for twenty years that there was reason to think you reside in when he was in new york that his wife  for unless we have jurisdiction first the agency has to acquire jurisdiction by issuing a summons on the seventy six zero three if they don't issue was something else to the taxpayer at his less than usual place of a boat we never that then under the powell factors the fourth of the factors is that all administrative steps under the code have been taking but we don't get to the even seventy six zero four until the agency itself summonses the taxpayer under seventy six zero three and that didn't happen and that's where we have a factual dispute because we we contend the that the evidence was conflicting when the internal revenue service sent the notices under seventy six zero nine they sent them to switzerland we put in declarations of taxpayers of witnesses who would say that mr mellon hadn't been in the apartment didn't reside in the apartment and th investigation starts in twelve mr frayne japans declaration talks about events in twelfth they waited two years they didn't summons this taxpayer until two thousand and fourteen and the case law is clear that you can test a sum it's on the date that it's issued if we're focusing on the date that the summons was issued in two thousand and fourteen mr mellon was no longer at fifty have as his last and usual place of abode for purposes of seventy six zero three if the agency never acquired jurisdiction over him then under seventy six and three he once in a summoned person for purposes of di report jurisdiction under seventy six so for that was a matter of discussion in the district or the agent acknowledged that he had received mail from mr mellon shortly before sending the complaint from a switzerland address but he averred that mellons fifth avenue apartment was his last and usual place of abode which is something distinct in the district court studiously avoided talking about two thousand and fourteen at a light most favorable to the age it was just making that assumption but what the record also contained was your client providing his address he's new york of the form said that the putting that is the address to receive mail is not going to establish residence so that the form doesn't ask for residence and asks for an address to get mail i mean mini people  many foreigners own real estate in new york city and you would not say the mere ownership of real estate made them subject to the internal revenue service taxation i mean that in a global world we have that that's one factor but we should have been allowed to put on evidence cross examine the witness as to the other factors including you know what the i r s records showed from his passport as to how many times he'd been in the united states during that period of time when you're using words like last and usual place of a boat as opposed to a dress that requires more of a prominence and the government yes the six zero nine place in this because it is not issued determinant because the words on all three statutes are different which makes for the the ambiguity i mean seventy six zero three talks about the less than usual place of abode that's for the agency to choir jurisdiction seventy six zero nine is provides notice because the internal revenue service has contacted third parties and that notice is sent to what the government knows is the last known address the best address to get mail i so in that i would not be issue but it would be relevant at a factual hearing to determine what is for purposes of seventy six zero three the last and usual place of abo i have your on it thank you very threshold had been met that would require an evidentiary hearing there wasn't a request either in connection with a motion dismissed or at the actual hearing that was held where there was limited argument there was no request beyond that which under this  circuit's president means that to the extent there was any right it has been waived the circuit is also held and this is i should say briefly this is a very different circumstance than clark this is not a circumstance number one where the taxpayer a question enter here a number one number two where there is plausible evidence showing bad faith and that was the thrust of the argument the question has never been and some in and mr mellon in bad faith it wasn't actually in connection with a legitimate investigation faith and so we are far outside of park there has been a waiver on that point and indifferent to that there's certainly no evidence that mr mellon has suggested he didn't have access to putting in some other form like a declaration or an af here to defend this he could say and he has and he could say this is how much time i spent at eleven o seven fifth avenue in two thousand and sixteen this is how much time i've spent in these other residences he hasn't done and he's been completely silent and said the evidence we have reggie you know went through some of the evidence the government put forward which is extensive in including mr mellon's own words and the response from mr mellon has not been to dispute the accuracy of any of those those documents but rather to say here declarations suggesting that he also spends time elsewhere including in europe he has residences in europe and there's certainly no inconsistency as the circuit held in the rule for context between those two things  seven fifth avenue had sufficient and issue of permanence under this court's rule and national development co to qualify as dwelling house or usual place of abode and it's difficult to see given that mr mellon still to this day has not disputed that has suggested the residence is in the us outside of new york and so on this record with the mountain of evidence the government put forward and the very limited evidence that's not inconsistent put forward by mr mellon i submit it is not fair for the district court to have found th personal jurisdiction was was correctly granted here i would also note just turning quickly to the power factors know that this is not an argument although mr mellon did reason issues with compliance under seventy six  three below and he argued that eleven or seventh avenue was not the last unusual place of abode which is you know one of the requirements and in terms of service under seventy six zero three he never raising or even under power he said that that what that what that does is it destroys subject matter jurisdiction he never is pal and so the district court didn't specifically address palin the burden shifting framework that would apply because it was simply never raised and therefore was waived but in any case in this context clearly the minimal threshold has been met for the government the burden which you have to mr mellon as this court and the supreme court has recognized that burden is a heavy one and he is certainly not disproved that eleven zero seven fifth avenue was in fact his last unusual place  abode the fact that he was staying at what appears to be his wife's family's swiss chalet for some period of time and doesn't disprove that eleven zero seven fifth avenue remained his last and usual place of abode even if he had spent some time outside u so i believe it is on the appendix ph to sixty five much if i may first we don't get to the powell standards until we first have jurisdiction under seventy six zero three personal jurisdiction and then that the district court has subject matter jurisdiction under seventy zero four we have made a special appearance to contest jurisdiction in this matter so that we raise the jurisdictional issue and jurisdiction is something that that should be proven by the moving party then with respect to the the standard review to the extent that he that we contend that the district court read out of the statute the words last and just went with residence  opposed to in seventy six zero three and seventy six supports always been sui generis all the cases cited in the oral opinion and the cases cited by the government always have a strong cite that you include this but there is no case that i
