Public international law eased by mutual deference one might think. And yet, he calledthedisciplineprivateinternationallawforareason:forhim,conflictoflaws could be resolved on the basis of universally understood laws and on genuinely privateconcerns.Savignywentfurtherandestablishedprivateinternationallawas anextensionofprivatelaw,withhardlyanyroleforpublicinternationallaw.Andyet, sovereigntyconcernsandpublicinternationallawremainedstronginotherschools, and the history of private international law has always been one of its relation to publicinternationallawaswell. Since the nineteenth century, relations between private and public international law have been of incessant concern. Is private international law really a subdis- cipline of international law, allocating adjudicatory and legislative competences amongindependentandsovereignstatesandnegotiatingconflictsthroughcomity? Is private international law an extension of domestic (private) law, laying out the outer boundaries of scope, and as such untouched by public international law? Or doesitstand,perhaps,inafruitfultensionwithpublicinternationallaw,atensionof mutualirritationandinspiration,mutualrestrictionandempowerment?

October2021 RalfMichaels Director,MaxPlanckInstituteforComparative andInternationalPrivateLaw ChairinGlobalLaw,QueenMaryUniversity London,England Preface Public International Law and Private International Law (or Conflict of Laws) are taughtinmostlawschoolsasseparatesubjects.PublicInternationalLaw,wewere told,dealswiththeconductandtherelationbetweenStatesorbetweenStatesand internationalorganisations.Ontheotherhand,PrivateInternationalLawdealswith private legal relations between citizens or corporations in two different countries, being international contracts, inter-country marriages, international torts, etc. We were told the term “Private International Law” is a misnomer as in reality it is nothing more than a branch of domestic law dealing with cases involving foreign elements.Aspartofnationallaw,sourcesofprivateinternationallawcanbefound in domestic sources depending on the legal system, either in statutes or in case laws or in combination of both. On the other hand, sources of public international law are those listed in Article 38 of the Statute of International Court of Justice, namely international conventions, international customary law, general principles of law recognised by civilised nations, judicial decisions and teachings of highly qualifiedpublicists.Disputesbetweencitizensorcorporationsofdifferentcountries aresettledinatypicalcourtsystem,eitherbyajurisdictionagreementorotherwise, or by other alternative dispute resolution mechanisms, such as arbitration. On the other hand, disputes between States will be resolved through political means and otherdiplomaticchannels,ifnotthroughtheInternationalCourtofJustice(ICJ).
