Methodology The goal of this work is to address a seemingly simple comparative question: can Polish law facilitate the English notion of gain-based remedies for breach of con- tract? The necessity to pose this question stems from an intense development of, mostnotably,Englishcontractlawonthesubjectofassessingremediesforbreachof contractbased,seemingly,onthebreachingparty’sgainsfromthebreach.Modern English case law recognizes that classic loss-based damages are not always an adequate remedy to protect the totality of a party’s interests when a breach of contract occurs. Hence, in certain cases, English courts applied a more creative approach in protecting an aggrieved party’s interests in contractual matters. This resultedinthecreationofgain-basedremedies.Thetheoreticalprinciplesunderlying gain-basedremediesarenotyetclearlyestablished;theycanbeeithercompensatory or restitutionary. For this reason, the work will address and apply a comparative analysisofbothprinciples. On a marginal note, this is not to say that English law has settled the analyzed problem unambiguously. To the contrary, English legal scholars do not agree on every aspect or understanding of gain-based remedies. These uncertainties will howeverbeclearlyunderlinedinthiswork. ItisfirstimportanttointroducethemethodIchoseinhandlingthecomparative law issue at hand. I will describe this in four short stages: the methodology I have chosen (Sect. 1.1), the question I have posed (Sect. 1.2), the way in which I will endeavor to answer that question (Sect. 1.3), and the overall structure of the work (Sect.1.4). ©TheAuthor(s),underexclusivelicensetoSpringerNatureSwitzerlandAG2023 1 D.Zatorski,Gain-basedRemediesforBreachofContract, https://doi.org/10.1007/978-3-031-25452-9_1 2 1 IntroductionandMethodology 1.1 The Methodology Konrad Zweigert and Hein Kötz keenly underline that there is no one systematic methodofcomparativelawandthatsuchamethodshouldbegraduallydiscovered through trial and error.1 Indeed, Geoffrey Samuel points out the multitude of difficultiescomparativelawposes,theissueofmethodologybeingaprimaryone.2 However, Zweigert’sand Kötz’sanswertothis problemisthat the“basic method- ologicalprinciple ofall comparativelawisthat offunctionality.”3 Idonotwishto stray from this approach, and methodologically this work draws inspiration from Zweigert and Kötz, as well Solène Rowan’s functional analysis of remedies for breachofcontract.4 Underafunctionalapproach“Lawistobeunderstoodintermsofwhatitdoes.”5 The method fits perfectly with this work’s topic, as it is problem-oriented, i.e. it looksataspecificprobleminonesystemandtriestoassesshowthatproblemwould be solved in another.6 Moreover, a functional approach “allows for the bringing together of two quite different objects by reference to their practical uses and purpose.”7 To achieve this I wish to apply what Esin Örücü called the functional- institutionalapproachinordertofindfunctionalequivalentsofinstitutionsinPolish andEnglishlaw.Thisentailsaskingquestionssuchas:“Whichinstitutioninsystem BperformsanequivalentfunctiontotheoneundersurveyinsystemA?”8 1.2 The Comparative Question The issue of a properly framed comparative question is of crucial importance. A research question cannot namely be too vague or too complex.9 Thus, a properly posedquestionisabalancingactbetweensimplicityandprecision. Moreover,acomparativequestionshouldrefertoaspecificproblem.AsGerhard Dannemanunderlines:“Comparativelegalenquiriesarefrequentlymadeaspartof an effort to improve a legal rule or institution which has been suspected or 1SeeZweigertandKötz(1998);seealsoSamuel(2014). 2SeeSamuel(2014),p.9. 3ZweigertandKötz(1998),p.34;seealsoid,at65. 4SeeRowan(2012)(“Sincelegalsystemsthatfacesimilarproblemsdonotnecessarilystructure theirsolutionsinthesameways,andmayalsoadoptdifferentterminology,comparativequestions havebeenconsideredinfunctionalterms.”). 5Cohen(1935),p.809;seealsoSamuel(2014),p.86. 6SeegenerallySamuel(2014),p.67. 7Id.,at65. 8Id.(referringtoÖrücü(2006),p.443. 9Seeid.,at31. 1.3 TheApproachTowardsAnsweringtheQuestion 3 recognized as a source of problems.”10 Therefore, the conclusion to any research projectincomparativelawshouldbeonethatisobtainableonlythroughthebringing together of two or more objects of comparison and consequently the research question should reflect this necessity.11 In other words, comparison should be a meanswhichshedlightontoaparticularlegalproblem. The legal problem in question is the inadequacy of traditional compensatory damages for breach of contract. This problem—as will be shown—is clearly evidenced in an enrichment without subtraction situation. It also pertains to Polish law and has not been tackled in Polish legal writing thus far. It also seems to be propertograpplethisproblemduetothefactthatlegalregulationsareundergoing violent changes while the current Polish regulation is—as Piotr Machnikowski pointed out—still strongly rooted in Western Europe’s late nineteenth and early twentieth century laws.12 This begs the question whether Polish law can still facilitatenewdevelopments.Consequently,IwishtoputPolishlawinthespotlight. Moreover,theanalysiswillbelimitedtobreachofcontract.Whatthismeansisthat the work will deal purely with contract law, thus excluding tort, administrative, criminal, or company law; it will also exclude fiduciary duties or pre-contractual duties.Thisdoesnotmeanhoweverthatcertainprovisionspertainingtothesebodies oflawwillnotbementionedatanytime. In opposition toPolishlaw, English law has been grapplingwith the aforemen- tionedproblemforsometime.Ithasprovidedanswersthroughtwogroundbreaking cases, which are at the heart of this work, i.e. Wrotham Park Estate Co. Ltd v. Parkside Homes Ltd13 (“Wrotham Park”) and Attorney General v. Blake14 (“Blake”).Duetotherevolutionary influenceofthesejudgments,Englishlawwill form the basis for comparison. Furthermore, other legal systems will serve as a helpfultoolinordertoshedmorelightonmoredetailedproblems. Takingtheaboveintoconsideration,IbelievethatthequestionIposemeetsthe prerequisites of a properly framed comparative question, namely: can Polish law incorporatetheEnglishnotionofgain-basedremediesforbreachofcontract? 1.3 The Approach Towards Answering the Question An additional step—having posed a properly-framed question—is to set out the functionofcomparison.Inotherwords,itisimportanttostatehowtheworkwilltry to tackle the posed question. In this regard two opposing approaches to a 10Danneman(2006),p.403. 11SeeSamuel(2014),p.26. 12SeeMachnikowski(2017). 13WrothamParkEstateCoLtdvParksideHomesLtd[1974]1WLR798[hereinafterWrotham Park]. 14Attorney-Generalv.Blake,[2001]1AC268(H.L.)(Eng.)[hereinafterAGv.Blake]. 4 1 IntroductionandMethodology comparativeworkexist:Zweigert’sandKötz’spraesumptiosimilitudinisontheone hand,andPierreLegrand’spresumptionofdissimilarityontheother.15Theformeris connected with harmonization proposals that “suggest that one central function of comparison is to look for similarities, and in fact this idea of similarity has been elevatedbyZweigertandKötzintoapresumption.”16Intheiropinion: [T]hecomparatistcanrestcontentifhisresearchesthroughalltherelevantmaterialleadto theconclusionthatthesystemshehascomparedreachthesameorsimilarpracticalresults, butifhefindsthattherearegreatdifferencesorindeeddiametricallyoppositeresults,he should be warned and go back to check again whether the terms in which he posed his originalquestionwereindeedpurelyfunctional,andwhetherhehasspreadthenetofhis researchesquitewideenough.17 Thelatter,ontheotherhand,arguesthat“oneshouldstartoutfromapresumptionof differencebecausepresumptionsofsimilaritycanleadtoatypeofcomparisonthat involvesadeductiveapproachwhichpresentsthedangerofeclipsingwholesections oftheobjectsofcomparisonandthiscanresultintheestablishmentof‘universalist myths’.”18 As far as functional methodology is concerned, both approaches have merit. Gerhard Danneman points out: “[C]omparing legal systems involves, at least to somedegreeexploringbothsimilaritiesanddifferences.”19Hegoesontoague: Thefunctionalcomparatistwillfindgreatestsatisfactioninunearthingsimilaritiesinresults whicharehiddendeepinsideajungleofdifferentstyles,methods,procedures,andsources oflaw–justascriticsoffunctionalismmayderivethegreatestpleasurefromuncovering hiddendifferencesevenwherethelawappearssimilar.20 From thisitemergesthatjust asframingtherightquestionwasabalancingact,so too is an approach towards similarity and dissimilarity. In this regard Danneman points out that “the proper balance between discovering common features and detecting contrasting features depends on the purpose of the enquiry, or the Erkenntnisinteresse.”21 As I have mentioned, the problem of this work comes from the inadequacy of traditional compensatory damages under Polish law. Hence, a need to tackle this problem arises. As I have also mentioned, English law—having responded to this problem—willserveasabasisforcomparison.Therefore,thepurposeoftheenquiry istofindasolutiontotheinadequacyofcompensatorydamagesbyaskingwhether PolishlawcanincorporateEnglishsolutions. I believe that the best approach for such a purpose of enquiry is a cautious presumption of similarity. This means that I will not presume similarity from the 15SeeSamuel(2014),pp.53–54. 16Id.,at53. 17ZweigertandKötz(1998),p.40;seealsoid.,at53–54. 18Samuel(2014),p.55(referringtoHeidmann(2006)). 19Danneman(2006),p.384. 20Id.,at395. 21Id.,at400.
