整或解除。而誠(chéng)實(shí)信用原則則要求當(dāng)事人在民事活動(dòng)中應(yīng)當(dāng)秉持誠(chéng)實(shí)、守信的態(tài)度，當(dāng)情事變更導(dǎo)致合同履行困難或不能時(shí)，應(yīng)當(dāng)允許當(dāng)事人根據(jù)誠(chéng)實(shí)信用原則進(jìn)行協(xié)商或請(qǐng)求法院進(jìn)行裁決。Thetheoreticalbasisoftheprincipleofchangeofcircumstancesmainlystemsfromtheprinciplesoffairnessandgoodfaithincivillaw.Theprincipleoffairnessrequiresthepartiestoabidebythevaluesoffairnessandjusticeincivilactivities.Whenchangesincircumstancesresultinunfairperformanceofthecontract,thepartiesshouldbeallowedtorequestthecourttoadjustorterminatethecontract.Theprincipleofgoodfaithrequiresthepartiestomaintainanhonestandtrustworthyattitudeincivilactivities.Whenchangesincircumstancesmakeitdifficultorimpossibletoperformthecontract,thepartiesshouldbeallowedtonegotiateorrequestacourtrulingbasedontheprincipleofgoodfaith.情事變更原則還體現(xiàn)了民法中的意思自治原則。意思自治原則強(qiáng)調(diào)當(dāng)事人在民事活動(dòng)中享有自主決定權(quán)，但當(dāng)情事變更導(dǎo)致當(dāng)事人之間的意思自治受到破壞時(shí)，應(yīng)當(dāng)允許當(dāng)事人通過(guò)情事變更原則來(lái)恢復(fù)合同的公平性和合理性。Theprincipleofchangeofcircumstancesalsoreflectstheprincipleofautonomyofwillincivillaw.Theprincipleofautonomyofwillemphasizesthatthepartieshavetherighttomakeindependentdecisionsincivilactivities.However,whenthechangeofcircumstancesresultsinthedestructionoftheautonomyofwillbetweentheparties,thepartiesshouldbeallowedtorestorethefairnessandrationalityofthecontractthroughtheprincipleofchangeofcircumstances.情事變更原則的歷史背景可追溯到古羅馬法時(shí)期，其理論基礎(chǔ)主要源于民法的公平原則、誠(chéng)實(shí)信用原則和意思自治原則。這些原則共同構(gòu)成了情事變更原則的核心價(jià)值，為處理合同履行過(guò)程中因情事變更導(dǎo)致的不公平現(xiàn)象提供了重要的法律依據(jù)和指導(dǎo)原則。ThehistoricalbackgroundoftheprincipleofchangeofcircumstancescanbetracedbacktotheancientRomanlawperiod,anditstheoreticalbasismainlystemsfromtheprinciplesoffairness,goodfaith,andautonomyofwillincivillaw.Theseprinciplescollectivelyconstitutethecorevalueoftheprincipleofchangeofcircumstances,providingimportantlegalbasisandguidingprinciplesfordealingwithunfairphenomenacausedbychangesincircumstancesduringcontractperformance.三、情事變更原則的適用條件與判斷標(biāo)準(zhǔn)TheApplicationConditionsandJudgmentStandardsofthePrincipleofChangeofCircumstances情事變更原則作為合同法中的一項(xiàng)重要原則，其適用條件和判斷標(biāo)準(zhǔn)具有相當(dāng)?shù)膹?fù)雜性和專業(yè)性。在適用情事變更原則時(shí)，必須滿足一定的條件，并采用科學(xué)的判斷標(biāo)準(zhǔn)，以確保合同的公平性和正義性。Theprincipleofchangeofcircumstances,asanimportantprincipleincontractlaw,hasconsiderablecomplexityandprofessionalisminitsapplicationconditionsandjudgmentstandards.Whenapplyingtheprincipleofchangeofcircumstances,certainconditionsmustbemetandscientificjudgmentstandardsmustbeadoptedtoensurethefairnessandjusticeofthecontract.情事變更的客觀存在：情事變更原則適用的前提是合同成立后出現(xiàn)了無(wú)法預(yù)見(jiàn)的、非當(dāng)事人所能控制的客觀情況的變化。這些變化可以是政治、經(jīng)濟(jì)、社會(huì)等方面的因素，如政策調(diào)整、市場(chǎng)波動(dòng)、自然災(zāi)害等。Theobjectiveexistenceoftheprincipleofchangeofcircumstances:Theprerequisitefortheapplicationoftheprincipleofchangeofcircumstancesistheoccurrenceofunforeseeableanduncontrollablechangesinobjectivecircumstancesaftertheformationofthecontract.Thesechangescanbepolitical,economic,social,andotherfactors,suchaspolicyadjustments,marketfluctuations,naturaldisasters,etc.情事變更對(duì)合同履行的影響：情事變更必須導(dǎo)致合同的履行變得不公平或不合理，或者使合同的目的無(wú)法實(shí)現(xiàn)。這種影響應(yīng)當(dāng)是實(shí)質(zhì)性的，而非微不足道的。Theimpactofchangesincircumstancesoncontractperformance:Changesincircumstancesmustcausetheperformanceofthecontracttobecomeunfairorunreasonable,ormakethepurposeofthecontractimpossibletoachieve.Thisimpactshouldbesubstantial,notinsignificant.當(dāng)事人無(wú)過(guò)錯(cuò)：適用情事變更原則時(shí)，當(dāng)事人應(yīng)當(dāng)沒(méi)有過(guò)錯(cuò)。如果是因?yàn)楫?dāng)事人的過(guò)錯(cuò)導(dǎo)致的情事變更，則不能適用該原則。Nofaultoftheparties:Whenapplyingtheprincipleofchangeofcircumstances,thepartiesshouldnotbeatfault.Ifthechangeofcircumstancesiscausedbythefaultofthepartiesinvolved,thisprinciplecannotbeapplied.非商業(yè)風(fēng)險(xiǎn)：情事變更應(yīng)當(dāng)屬于非商業(yè)風(fēng)險(xiǎn)范疇，即無(wú)法通過(guò)正常的商業(yè)判斷來(lái)預(yù)見(jiàn)和避免的風(fēng)險(xiǎn)。Noncommercialrisk:Changesincircumstancesshouldfallunderthecategoryofnoncommercialrisk,whichreferstorisksthatcannotbeforeseenandavoidedthroughnormalcommercialjudgment.合理預(yù)見(jiàn)標(biāo)準(zhǔn)：在判斷情事變更是否適用時(shí)，應(yīng)當(dāng)考慮當(dāng)事人在合同訂立時(shí)是否能夠合理預(yù)見(jiàn)到情事變更的發(fā)生。如果情事變更的發(fā)生是當(dāng)事人能夠合理預(yù)見(jiàn)的，則不能適用情事變更原則。Reasonableforeseeabilitystandard:Whendeterminingwhetherachangeincircumstancesisapplicable,considerationshouldbegiventowhetherthepartiescouldreasonablyforeseetheoccurrenceofthechangeincircumstancesatthetimeofcontractformation.Iftheoccurrenceofachangeincircumstancesisreasonablyforeseeablebythepartiesinvolved,theprincipleofchangeincircumstancescannotbeapplied.公平合理標(biāo)準(zhǔn)：情事變更的適用應(yīng)當(dāng)符合公平合理的要求。在判斷情事變更是否導(dǎo)致合同履行變得不公平或不合理時(shí)，應(yīng)當(dāng)綜合考慮合同雙方當(dāng)事人的利益、合同履行的難度、情事變更對(duì)合同目的實(shí)現(xiàn)的影響等因素。Fairandreasonablestandards:Theapplicationofchangesincircumstancesshouldmeettherequirementsoffairnessandreasonableness.Whendeterminingwhetherchangesincircumstanceshaveledtounfairorunreasonableperformanceofthecontract,comprehensivec

law,playsanirreplaceableroleinensuringthefairnessandjusticeofbothpartiestothecontract.However,inthelegalpracticeofourcountry,therearestillsomeproblemsintheapplicationoftheprincipleofchangeofcircumstances,whichneedtobefurtherimproved.ThefollowingareseveralsuggestionsforimprovingtheprincipleofchangeofcircumstancesinChineselegalpractice:應(yīng)明確情事變更原則的適用范圍。在現(xiàn)行法律中，對(duì)于情事變更原則的適用范圍并沒(méi)有明確的規(guī)定，導(dǎo)致在實(shí)踐中存在較大的不確定性。因此，建議在未來(lái)的民法典或相關(guān)司法解釋中，對(duì)情事變更原則的適用范圍進(jìn)行明確界定，以便法官在實(shí)踐中能夠準(zhǔn)確把握。Thescopeofapplicationoftheprincipleofchangeofcircumstancesshouldbeclearlydefined.Incurrentlaws,thereisnoclearprovisionforthescopeofapplicationoftheprincipleofchangeofcircumstances,whichleadstosignificantuncertaintyinpractice.Therefore,itisrecommendedtoclearlydefinethescopeofapplicationoftheprincipleofchangeofcircumstancesinfuturecivilcodesorrelevantjudicialinterpretations,sothatjudgescanaccuratelygraspitinpractice.應(yīng)確立情事變更原則的適用標(biāo)準(zhǔn)。在實(shí)踐中，如何判斷情事是否發(fā)生了變更、變更的程度如何、是否影響了合同的履行等問(wèn)題，都需要一個(gè)明確的標(biāo)準(zhǔn)。因此，建議通過(guò)司法解釋等方式，確立情事變更原則的適用標(biāo)準(zhǔn)，以便法官在實(shí)踐中能夠統(tǒng)一尺度，避免濫用或誤用情事變更原則。Theapplicablestandardsfortheprincipleofchangeofcircumstancesshouldbeestablished.Inpractice,aclearstandardisneededtodeterminewhetherthesituationhaschanged,theextentofthechange,andwhetherithasaffectedtheperformanceofthecontract.Therefore,itisrecommendedtoestablishtheapplicationstandardsoftheprincipleofchangeofcircumstancesthroughjudicialinterpretationandothermeans,sothatjudgescanunifythescaleinpracticeandavoidabusingormisusingtheprincipleofchangeofcircumstances.再次，應(yīng)完善情事變更原則的程序性規(guī)定。在現(xiàn)行法律中，對(duì)于情事變更原則的程序性規(guī)定較為簡(jiǎn)單，缺乏具體的操作流程和保障措施。因此，建議在未來(lái)的民法典或相關(guān)司法解釋中，對(duì)情事變更原則的程序性規(guī)定進(jìn)行完善，包括申請(qǐng)程序、審查程序、裁決程序等，以確保情事變更原則能夠得到公正、高效的應(yīng)用。Onceagain,theproceduralprovisionsoftheprincipleofchangeofcircumstancesshouldbeimproved.Incurrentlaws,theproceduralprovisionsfortheprincipleofchangeofcircumstancesarerelativelysimple,lackingspecificoperationalproceduresandsafeguardmeasures.Therefore,itisrecommendedtoimprovetheproceduralprovisionsoftheprincipleofchangeofcircumstancesinfuturecivilcodesorrelevantjudicialinterpretations,includingapplicationprocedures,reviewprocedures,arbitrationprocedures,etc.,toensurethattheprincipleofchangeofcircumstancescanbeappliedfairlyandefficiently.應(yīng)加強(qiáng)對(duì)情事變更原則的宣傳和培訓(xùn)。情事變更原則是一項(xiàng)較為復(fù)雜的法律原則，需要法官和當(dāng)事人都有一定的法律素養(yǎng)和理解能力。因此，建議加強(qiáng)對(duì)情事變更原則的宣傳和培訓(xùn)，提高法官和當(dāng)事人的法律意識(shí)和應(yīng)用能力，以便更好地實(shí)現(xiàn)情事變更原則的價(jià)值和功能。Weshouldstrengthenthepromotionandtrainingoftheprincipleofchangingcircumstances.Theprincipleofchangeofcircumstancesisacomplexlegalprinciplethatrequiresboththejudgeandthepartiesinvolvedtohaveacertainleveloflegalliteracyandunderstanding.Therefore,itisrecommendedtostrengthenthepromotionandtrainingoftheprincipleofchangeofcircumstances,improvethelegalawarenessandapplicationabilityofjudgesandpartiesinvolved,inordertobetterrealizethevalueandfunctionoftheprincipleofchangeofcircumstances.完善情事變更原則在中國(guó)法律實(shí)踐中的應(yīng)用是一項(xiàng)長(zhǎng)期而艱巨的任務(wù)。需要我們從多個(gè)方面入手，不斷提高情事變更原則的適用水平，為實(shí)現(xiàn)社會(huì)的公平和正義貢獻(xiàn)力量。Theap
