mistake for purposes of all fifteen's relation back to the relation back doctrine reflects the common sense idea that a party should not be penalize for making a genuine and reasonable mistake when suing or naming a prospective defen reasons first suing a john doe defendant is not a mistake within the plain language or ordinary dictionary definition of standing up the term nd nearly every circuit that has addressed this exact question has determined that assuming a john doe defendant is not a mistake for purposes of all fifteen and rd the history an amendment to rule fifteen further support that it does not apply to this situation so turning to my st point  principle case that the district excuse me that the district court relied on was the supreme court's two thousand and ten decision in versus kosta co chair where a plaintiff who had been injured aboard a cruise ship sued who she believed to be the owner and operator the cruise ship which was a company called coast a cruise now in actuality the owner operator of the ship was a company named kosta koshare and coast to cruise acted as the marketing and sales agent for that other corporation now the supreme court stated that even though the plaintiff understood the existence or knew about these two different entities that did not foreclose the possibility that she in it because she misunderstood the corporate relationship between these two entities that is very different from the john doe situation where a what the plaintiff is doing is as affective when using the john doe pleading device as a benchmark to  stamp in time the moment they filed their case and then later on seeking to amend the complaint to bring in the party once they discovered that person so that is very different from the traditional cases where the relation back applies where it's a conflation of identity between related entities or related persons and if you look at the definition that was actually cited in the crabs case it's premises a mistake on iraq action or a wrong step now the district court in its where they defined in the state as a wrong action or statement proceeding from faulty judgment inadequate knowledge or inattention of the main problem is that's when you're naming a john doe defendant there is no wrong step or wrong action you simply just don't have that information but you haven't made an error in terms of conflating you know that fictitious person with an actual real person just so you guys like to ask a question about that reading of crops came in we appreciate your submission here as to how we should read crop ski versus perhaps how the district court or district court just or courts read the crap scheme there's also this alternative argument that's been presented in the amicus brief i'm specifically focusing in on pages twenty two dollars to twenty six dollars in which they make reference to illinois interpretation of crop ski specifically with regard to rule fifteen  don't i would disagree that it undercuts our argument and i'm from that what you're referring to just brennan and i think there's two things to say about that one that's not what the district court decided in this case in fact there was no mention of that particular provision of the rule but secondly i think it's really a red herring because the illinois standard and the federal standard there is no difference between the two in fact the illinois rule was amended to bring itself into compliance with the federal rules so it takes its cue from the federal rules not vice versa and there's been no definitive decision by the illinois supreme court about the relation back and the scope of that provision and this court has in fact stated that there is essential you know difference is simply not interpreted differently either at the state level or at the federal level and that again goes back to the commonsense understanding of what is aimed state you know if you were asking you know your friend about sports history and you ask  them who won the super bowl last year and they told you i don't know i don't watch football you wouldn't say to them oh you've made a mistake you see that your mistake and you would say would they just don't know that now if they said that you know the chicago bears won the super bowl then you might tell them that they've ma because they're taking that wrong step or wrong actions of course they didn't win but i think that goes to is just the plain language understanding of what is a mistake and the district court in its decision and other other court seeing other courts that have decided this issue have primarily based their interpretation concerns on the issue of fairness but i want to dress that because i think that that is really not a concern that should be raised in in determining  mistake it is st of all it's congress and the rules committee that effectively determines what is an is not fair those are the institutions that are best situated to make that determination and consider the consequences of an act importantly there are already doctrines in place that alleviate any concerns about unfairness things like as portable tolling equitable stoppel those things are already in place and allow for that fairness aspects to be alleviated when you have a particular class of plaintiff or you have someone who for reasons beyond their control can't it's bring their claims in a timely manner and that is essentially what every circuit that has addressed this issue has come to the conclusion on  merits of your positions what's your view on whether we should remain and for consideration of the application of equitable tolling here i think it will be appropriate judge jury man for acquittal tolling precisely because that decision was not reached by the district court so it should in fairness need sent back down to have those arguments ruled upon about whether or not it's going to apply in this case and that's what we're asking the court to do and it's precisely because these other doctrines exist that we're saying that there's no need department of corrections but even in that case they didn't actually make the determination that suing the john doe defendant is a mistake with base they actually didn't apply relation back at all because they found that the notice aspect had met but what they said was in a footnote they made some concerns or some remarks about the policy of having this type of rule and whether or not it was good policy or not and they urged the rules committee actually to amend the rule to change it to make it explicit that suing a john doe defendant could be a mistake because it's done based on a complete lack of knowledge but that request which was made almost twenty years ago at this point has gone on acted upon and we still have the current  were suing the wrong government entity in relation to medicare and social security administration and you can look at the committee notes for that but they were trying to correct that problem where the plaintiff misunderstood who they should have been suing but that is not a problem when we're talking about the john doe context because again the plaintiff understands exactly what they're doing they understand that they're naming this fictitious person and then they're seeking to amend the complaint later on the problem is that that's why we have a statute of thank you your honor good morning in may it please the court i'd like to start this morning by addressing a question that was asked of appellants counsel specifically the application of walls between c one  to this case from the apple lease perspective from our perspective that is in fact controlling and that mandates a judgment in favor of our client the reason i say that is the illinois they were trying to figure out whether relation vachss should apply in a situation where it including a situation just like ours the key case to which i would direct the court's attention is one that cited in the amicus brief it's illinois one of those questions specifically was whether lack of knowledge regarding the identity of a potentially culpable party could be mistaken identity such that naming that party it not only on prior illinois case law but also specifically on crop ski crops he was a watershed case with you know from the united states supreme court and it made clear that the will the rules of civil procedure generally and will between specifically should be read to maximize the likelihood that cases will be decided on their merits and not on a procedural technical the i'd like to address another point that was raised during the appellate argument and that is specifically about other circuits that have dealt with this particular question of and by particular question i mean john doe and whether naming the actual defendant after the statute of limitations has lapsed can relate back to a john doe having been named before the lapse of the statute of limitations but we addressed it somewhat in our brief i want to specifically make a couple of points that we didn't make in our brief that i think go specifically to what counsel for sierra and the th circuit in haggling did specifically deal with whether or not the crops case dealt with also a john doe situation or whether it should be applied to a john doe situation and in both those cases the nd circuit in the th circuit decided that it should not for true reasons we believe that those cases are wrongly decided st because it missed those cases mis read krupp skee they joseph case which was decided approximately nine months after and and this court correctly understood that the crux key case cut the legs out from under what had been the rule in this circuit as articulated in the whole case decided several you're wrong so we think that it's a misreading of crops but also i turned back to the fifteen c want to a argument because the state of illinois specifically has made clear that in a situation like ours it would relate back to the filing of the original complaint that should also control this court's decision here one other thing so that i don't forget in terms of whether or not the case should be remanded regardless of the court's decision here i concur with what my colleague counsel for the appellant said this case should be remanded back because there's been absolutely no factual development what happened below is we filed w respond to the argument that in crop ski you really are dealing with confusion about corporate identity s and what we might think of more naturally as  constituting you know a mistake an unintentional error that way and in this situation you're not in any way dealing with an unintentional error in other words what concerns me about your position is it seems like we have to interpret the word mistake not in alignment with its ordinary common meaning as we did in the hall but rather somehow view corrupt cr as giving us a mandate to construe mistake as like a term of art now i understand but i think i understand your question wrong let me try to address it this way st of all i've absolutely did not deal with our situation croaky did not deal with john goes the reasoning in krupp ski we believe is also a political heat because of his discussion of the predisposition to decide cases on their merits but it's interesting that you also raise hall even though hall was affectively over war by the joseph court there's a there's a discussion there that directly relates naming a john doe defendant with naming an incorrect party so in other words in the hall that they that the court decided that naming a date coming back and naming a correct party after an incorrect party had been name was no different than having named a john doe  as a defendant and so the court weighted those two things from our perspective they're the same thing here also the definition the very definition of mistake that was written into the supreme court opinion in crop ski talks about actions taken on in adequate knowledge that is flatly where we are here and something i think needs to be addressed we see justice in this pacific case on behalf of our client written want to defend what the defendants appellants asked for here is that it could never be a mistake to name a john doe as a defendant and then come back after the statute of limitations and have the naming of the actual defendant relate that to that early earlier why we think that is flatly incorrect we think that it would be grossly unfair to people exactly in the position of client what we want to do here is develop a factual record for the district court it's absolutely correct that we still have equitable tolling arguments and we feel strongly about those as well but here what we're here to talk about today is whether or not naming the actual defendant after having named john doe can ever relate that the question presented by appellants here is whether it can ever relate that and they argue that it never ever can that would be a draconian ruling we think that it's flatly incorrect we should remember that our client was a young man in his early twenty's incarcerated still incarcerated today doing the very best that he could to identify who had who it was that attacked him in his pro se complaint he named the shift where they worked he gave very detailed descriptions of what happened to him and approximately what time of day and as the day went on and as he was waiting for medical attention he did absolutely everything that he could do then the district court recognizing him as a pro se plaintiff did exactly as they as he should have done the district court looked at the complaint decided that it was not frivolous decided that it did state a cause of action that should be addressed and he said he didn't he ordered that it be served on the sheriff so that the sheriff might help the plate th breakthrough in cases where the plaintiff didn't know who threw the brick at her so that is very different again from the john doe situation where he understands who he is suing and understands what he is doing and the converse is really the opposite as a judge  hit on the head is what you get is you get gamesmanship on you know plaintiffs bringing the case at the very end of the litigation period the limitations period which is what happened in this case where he you brought the case seventeen days before the statute of limitations
