Recent victory case analysis: Mazen Al Ramahi v. Hungary

In an award issued on April 19, 2021, an ICSID tribunal dismissed all claims on the merit in Mazen Al Ramahi v. Hungary. The award is yet to be made public.


  • The dispute related to Mr. Al Ramahi’s investment in several hotels in Budapest, as well as liquidation proceedings initiated against ZeinaHotel, the company through which he owns Continental Hotel Zara.
  • Ramahi opened Continental Hotel Zara in 2010.
  • In 2014, a supplier filed liquidation proceedings against ZeinaHotel.
  • ZeinaHotel had been fined for trademark infringement, yet the fine was overturned in 2014.
  • After ZeinaHotel reached an agreement with its creditors, the liquidation proceedings ended in 2016.
  • Ramahi filed his ICSID claim in 2017, relying on the Hungary – Jordan BIT.

Tribunal constitution

Tribunal’s decision

The tribunal upheld jurisdiction over the dispute but dismissed all of Mr. Ramahi’s claims on the merits. It also awarded Hungary a portion of its costs.

Legal rationale

The Award is currently subject to a confidentiality order, so the reasoning behind the decision is unfortunately not available.

Interview with Michael Ostrove (Global Co-Chair of DLA Piper’s International Arbitration group)

  1. Congratulations on the Mazen Al Ramahi v. Hungary case! What does this significant victory mean for the firm?

We are delighted with this result for Hungary. We are Hungary’s “go-to” law firm for public international law advice, and currently we are advising on six disputes for the State. We have a truly excellent disputes team in Budapest who is working in conjunction with other PIL specialists based in Paris, Madrid, and New York. A case like this absolutely hits DLA Piper’s sweet spot insofar as we are able to advise on complex local law issues (in this case parallel court litigation and bankruptcy proceedings) in conjunction with providing the highest quality investment law advice.

This latest success is a testament to DLA Piper’s ability to handle complex investment treaty arbitrations and secure great results for our State clients. This victory follows other significant wins in recent years for Kenya, Timor Leste, Oman, and Moldova, among others.

  1. You also recently achieved a win for the investor in the De Sutter and others v. Madagascar (II) What important implications does this case have on ISDS today?

The De Sutter case is one of the relatively rare instances of a tribunal finding a violation of the full protection and security obligation. The award provides a detailed analysis of this standard, commonly found in BITs. In this case, a mob led by disgruntled workers broke into the secure compound housing the claimants’ garment factory and other businesses and proceeded to plunder and burn the factory while the Malagasy security forces stood by and watched. The tribunal held that the lack of intervention of the Malagasy forces amounted to a breach of the full protection and security standard.

As Madagascar raised approximately 40 objections to jurisdiction and admissibility, the award also contains interesting analysis on a wide array of issues, including some important analysis on the applicable law relevant to the determination of nationality under the ICSID Convention.

  1. What are the key challenges you see on intellectual property issues in investor-State dispute settlement?

Intellectual property issues arise in a wide array of investor-State cases. Interestingly, they even arise in cases relating to mining projects. An investor may claim that geological studies and the like form part of the IP of the project. However, such documents are commonly required to be submitted to the State as part of the licensing application process. The question then arises whether there is still intellectual property in such studies or whether any rights are lost. Of course, this question will be very fact-dependent. This question arose in the Cortec v. Kenya case which my colleagues handled, and which resulted in an outright victory for our client, Kenya. In the annulment decision, the Committee was not persuaded by the investor’s arguments that it retained any IP in documents “freely given” to the State.

  1. What are your thoughts on the global transparency of arbitration outcomes where parties consent to publication or redacted publication?

Moves to promote greater transparency in investor-State disputes, such as the Mauritius Convention and the UNCITRAL Transparency Rules, have had a very positive impact in the field. DLA Piper has been fortunate to participate in some of the landmark cases in that regard, such as the BSG Resources v. Guinea matter, which included one of the first live-streamed arbitration ICSID hearings. On the back of the investor-State trend, we have seen various initiatives in the commercial arbitration world with similar aims. Here I am thinking of the recent amendment to the ICC Rules making publication of awards and procedural order the default position, subject of course to any objections raised by the parties.

  1. As one of the world’s largest law firms, DLA Piper has developed sizeable arbitration teams worldwide. Could you share with us how the expansion generates cross-border disputes work for the firm?

DLA Piper has seen phenomenal growth in its arbitration team in recent years, both in terms of internal promotions and lateral hires. One consistent piece of feedback we receive from clients is that they appreciate having lawyers on the ground in the relevant jurisdiction to the dispute who work hand-in-hand with other team members across the globe. We invest a lot of time in understanding where our clients have operations so that we can offer a commercially driven solution when a dispute arises. Our wide global footprint is a significant advantage for developing work as it gives us much better visibility of potential flashpoints which could give rise to disputes.

  1. As a significant part of your practice is focused on Africa, in your view, what are the key developments in the investment arbitration scene with the African continent today?

African practitioners and governments are really at the forefront of some of the most innovative developments in investment arbitration in recent years. As with our work in other regions of the world, it is crucial for us to be working with local practitioners on our Africa-related cases. The increasing experience and expertise of these lawyers are going to change the face of arbitration not only on the Continent but globally. Governments are not being left out. The 2016 Nigeria-Morocco BIT was one of the first in the new generation of BITs which sought to ensure that social and environmental concerns relating to foreign investment were addressed expressly.

One of the most eagerly awaited developments is the Investment Protocol of the African Continental Free Trade Agreement. Having created a single market of 1.2 billion people and a combined GDP of more than USD 2.2 trillion, it remains to be seen what investment protections will be granted to intra-African investors and whether investment arbitration will be embraced as the preferred dispute resolution mechanism.

  1. You have particular experience with the OHADA arbitration framework. Could you tell our readers more about your experience? What are the important challenges when arbitrating under the framework?

Especially following the most recent reforms to the OHADA Uniform Arbitration Act, the legal framework itself includes several innovations that make it very attractive. An example is simplified enforceability throughout the OHADA Zone. Moreover, the CCJA is developing a solid jurisprudence in arbitration and demonstrating that its judges master the field. OHADA arbitration does remain a work in progress, however, and there have been times when the CCJA could act more quickly and aptly to correct errors by various State courts. The biggest challenge within OHADA arbitration is thus dealing with local courts that are sometimes unfamiliar with arbitration, under-resourced, and unable to handle delaying or other disruptive tactics. But this is a challenge that other parts of the world have faced and overcome in the past, and given the number of devoted and talented practitioners in the field, there is reason to be optimistic that OHADA arbitration will continue to develop and thrive.

The ICSID tribunal suspended the case pending the finalization of the settlement.

  • In 2013, the firm helped Moldova defeat a €40 million ICSID claim brought by Franck Charles Arif under the France-Moldova BIT relating to duty-free concessions.
