The present article addresses the issue, whether in international law there exists pre-contractual responsibility (culpa in contrahendo). If such a responsibility indeed exists it will play a significant role not only in State-to-State relations, but also in the relations between States and private investors, given the fact that currently, on the virtue of investment treaties, private entities have rights to lodge claims against states before arbitration tribunals, which employ international law in their judgements. Hence, determination whether responsibility for culpa in contrahendo exists in international law, will allow to establish, whether private entities may base the claims on that ground, and if such course of action is advantageous. The proposed analysis will be based upon sources of international law, such as treaties, custom, general principles of law, as well as judicial and scientific authorities – and additionally also relevant practice in chosen States’ legal practice.

These standards were introduced at four international organizations and supranational associations: 1) the European Union; 2) the Council of Europe; 3) the Organization for Economic Cooperation and Development; 4) the Commonwealth of Independent States. The article states that the key reason for the introduction of standards for the regulation of lobbying at the international level was considerable corruption in the adoption of legal acts. It is concluded that latent and unregulated lobbying can seriously undermine public confidence in the institution of government, especially in the countries of the so-called “new democracy”. International regulation of lobbying takes the form of resolutions, procedural rules, guidelines, recommendations and model legislation. Notably, the first steps towards international regulation of lobbying were taken by the institutions of the European Union. Today EU standards for the regulation of lobbying is based on a series of articles set out in the EU-founding treaties and the Charter of Fundamental Rights of the European Union. EU standards for the regulation of lobbying influence not only the EU Member States, but it also extends to EU Partner Countries. Significant steps in the implementation of international standards for the regulation of lobbying are being constantly carried out by the Council of Europe. The establishment of CE standards for the regulation of lobbying is reflected in the activity of statutory bodies of the Council of Europe and its semi-autonomous bodies. In recent years a lot of work on the strengthening of international standards for lobbying regulation has been done by the Organisation for Economic Co-operation and Development. To help address the concerns with transparency and integrity in lobbying, the OECD Member Countries adopted in 2010 a Recommendation on Principles for Transparency and Integrity in Lobbying as guidance to decision-makers on how to promote good governance in lobbying. Another international organization, which began to regulate actively the practice of lobbying is the Commonwealth of Independent States. In order to intensify the work concerning legislative regulation of lobbying in the member countries of the CIS, at the XXII Plenary Session of the Interparliamentary Assembly of the CIS member states the Resolution No. 22-16 of November 15, 2003 was adopted, which approved a model law “On regulation of lobbying activity in state authorities”.
