Germany Amends Implementing Act to the Hague Evidence Convention, No Longer Forbidding Pre-Trial Discovery of Documents

It is a well-recognized principle of international law that judicial power ends at the respective state’s border. Consequently, courts need to request judicial assistance if they wish to obtain evidence outside of their jurisdiction. Previously, German courts receiving a request for pre-trial discovery from a common-law jurisdiction would not execute this request – regardless of its content or origin. Due to a recent amendment to Germany’s Implementing Act to the Hague Convention on the Taking of Evidence Abroad in Civil or Commercial Matters (“Hague Evidence Convention”)[1], this situation may change in the future, thus, allowing for pre-trial discovery if certain conditions are met. Nevertheless, due to detailed prerequisites needed to execute a request, Germany is still taking a rather hesitant approach towards pre-trial discovery compared to other jurisdictions.

Status quo ante

In Germany, questions of judicial assistance for courts located outside of the European Union and regarding the taking of evidence are governed by the Hague Evidence Convention.[2] The Convention entered into force on October 7, 1972. Designed as a “bridge between common and civil law”[3], it established standardized procedures for handling Letters of Request to collect evidence abroad. As of today, 64 countries have become a contracting party to the Convention, including the US, the UK, China, the Russian Federation and a majority of European states.[4]

The Convention covers all types of taking evidence, including pre-trial discovery of documents. Nevertheless, due to concerns about invasive requests from common-law jurisdictions, the Hague Conference on Private International Law decided to allow Contracting States to declare a reservation regarding pre-trial discovery (Article 23).[5] So far, 28 countries have asserted an absolute, non-particularized reservation, while 19 states have declared that they would only execute a request within the meaning of Article 23 if it fulfilled certain requirements.[6]

When Germany joined the Hague Evidence Convention in 1977, it also decided to make use of Article 23, opting for a general, non-particularized reservation. In the following, it adopted the Implementing Act to the Hague Convention of 15 November 1965 on the Service Abroad of Judicial and Extrajudicial Documents in Civil or Commercial Matters and the Hague Convention of 18 March 1970 on the Taking of Evidence Abroad in Civil or Commercial Matters (“Implementing Act”). Section 14 of the Implementing Act provided that requests for mutual assistance relating to proceedings under Article 23 of the Convention shall not be executed.[7] Consequently, any requests concerning pre-trial discovery would not be carried out in Germany[8] – until now.

The new German rule

On January 19, 2022, the Federal Ministry of Justice submitted a draft amending the Implementing Act. The bill was passed by the Bundestag and the Bundesrat and will enter into force on July 1, 2022.[9] It includes a revision of Section 14 of the Implementing Act, converting the previous absolute reservation under Article 23 of the Hague Evidence Convention to a qualified, particularized one. The new Section 14 of the Implementing Act will provide that courts shall execute requests for mutual assistance on pre-trial discovery of documents if the following five requirements are met:

  1. The documents to be produced are specified in detail,
  2. the documents to be produced are of direct and clearly identifiable importance for the proceedings in question and their outcome,
  3. the documents to be produced are in the possession of a party involved in the proceedings,
  4. the request does not violate essential principles of German law, and,
  5. in case the documents to be produced contain personal data, the requirements for transfer to a third country pursuant to Chapter V of Regulation (EU) 2016/679 of the European Parliament and of the Council of 27 April 2016 on the protection of individuals with regard to the processing of personal data, on the free movement of such data and repealing Directive 95/46/EC (General Data Protection Regulation) (“GDPR”) are met.[10]

With the amendment, Germany follows a recommendation of the Special Commission of the Hague Conference on Private International Law that has been reviewing the Evidence Convention and its application.[11] The Commission stated that the purpose of Article 23, namely “to ensure that a request for the production of documents [is] sufficiently substantiated so as to avoid requests whereby one party merely seeks to find out what documents may generally be in the possession of the other party to the proceeding”[12], could easily be achieved with a particularized declaration similar to the one submitted by the UK.[13] Germany had already tried to introduce an almost identical version of the new Section 14 in 2017 but withdrew the amendment from the bill at the last minute. At the time, the Judicial Affairs Committee doubted the benefit of the proposed rule and justified the withdrawal by arguing that the taking of evidence aimed at stating which documents were in one’s possession (“Ausforschungsbeweis”) was inadmissible[14] – even though such requests were (also) excluded in the 2017 draft and the German Federal Constitutional Court had explicitly stated in 2007 that pre-trial discovery per se was constitutional and did not violate fundamental principles of German law.[15] The unsatisfactory state of limbo since then has now been rectified by the modification.

Still, the recent amendment shows that Germany is taking a rather critical approach towards pre-trial discovery, defining more detailed and extensive requirements than the UK or other jurisdictions. Nevertheless, looking closely at the new provision, only one requirement may lead to blatant restrictions of document production. While the first two conditions reflect the basic rationale of the UK declaration to prevent unreasonable ‘fishing expeditions’, the fourth and fifth prerequisite are merely declaratory. Article 12 lit. b of the Evidence Convention already provides that a court may refuse execution of a request if it would prejudice the state’s sovereignty or security, thus containing an ordre public-reservation. Furthermore, German courts may also refer to potential violations of German local law to turn down a request pursuant to Article 11 of the Convention. Similarly, compliance with the GDPR as prescribed in Section 14 No. 5 of the Implementing Act is required within the EU in any case, thus creating no additional obstacles.[16]

The most significant limitation to pre-trial discovery requests, however, is the exclusion of third parties not involved in the proceedings (No. 3). No other Contracting State has issued a similar declaration. German civil procedure law does not recognize such a restriction either: In domestic proceedings, third parties can be obliged to produce documents pursuant to Section 142 of the German Code of Civil Procedure.[17] As a result, the Implementing Act’s new provision ultimately contradicts the German legislator’s intention to eliminate fundamental differences in obtaining evidence in domestic and international cases.[18]

Implications for future proceedings

The recent amendment will enable German courts to execute pre-trial discovery requests from foreign courts. Currently, Australia, Barbados, India, Syria, Seychelles, Singapore, South Africa, Sri Lanka, the UK and the US utilize this type of evidence taking and are Contracting States to the Evidence Convention.[19] Among these, requests from the US and the UK most likely have the greatest practical relevance.[20]

It remains to be seen whether Germany’s change in direction will have a significant impact on future transnational litigation. In the past, instead of referring to the Hague Evidence Convention, foreign courts often applied their own procedure law extraterritorially to fulfill pre-trial discovery requests in Germany.[21] It is unlikely that the recent amendment will put a halt to this practice. As it happens, the previous draft to the Implementing Act from 2017 had expressed the hope that an amendment would lead US courts to preferentially refer to the Hague Convention because they could count on an effective and fast execution of their requests. Whether this will actually happen is debatable – and quite possibly, somewhat naïve. Be that as it may, the new German Implementing Act offers foreign courts and parties an additional route to deal with pre-trial discovery request in Germany – and ultimately furthers the Hague Convention’s initial objective to strengthen the often shaky bridge between civil and common law.
