INTRODUCTION AND THE PARTIES

1. This case concerns claims brought by (i) Mainstream Renewable Power Ltd, (ii) International Mainstream Renewable Power Limited, and (iii) Mainstream Renewable Power Group Finance Ltd, three private companies limited by shares incorporated in Ireland, and (iv) Horizont I Development GmbH, (v) Horizont II Renewable GmbH, and (vi) Horizont III Power GmbH, three limited liability companies incorporated in Germany (together, the "Claimants"), against the Federal Republic of Germany ("Germany" or the "Respondent").

2. The dispute arises out of regulatory measures taken by the Respondent regarding its wind energy regime, which allegedly affected the Claimants' wind energy projects, resulting in a loss to their investments.

3. This ruling concerns the Respondent's preliminary objection pursuant to Rule 41(5) of the ICSID Rules of Procedure for Arbitration Proceedings (the "ICSID Arbitration Rules").
