Clause 1 of the Resolution on the Formation of the Republic of Estonia, the Republic of Latvia and the Republic of Lithuania Interparliamentary Assembly (the Baltic Assembly) adopted at the meeting of delegations of Estonian, Latvian and Lithuanian Supreme Councils, provided that the Regulations of the Baltic Assembly were to be drafted by the joint working group of the Baltic countries and the Nordic Council before the Estonian, Latvian and Lithuanian parliamentary co-operation organisation has been formed itself.
At the 3rd Session, on October 31, 1993, the Regulations of the Baltic Assembly were enacted determining its structure and the basic principles of cooperation. The Regulations of the Baltic Assembly were supplemented and amended three times: at the 5th Session in November 1994, at the 10th Session in April 1997, and at the 13th Session in November 1998. Numerous deficiencies were found in the Regulations of the Baltic Assembly. For example, the competence, functions and rights of its bodies were not clearly defined; it was not stated which was the supreme governing body; it was not specified on what occasions extraordinary sessions could be convened, who would be the convener and how the agenda should be drawn up; it was not clear if the Budget and Audit Committee was a permanent or an ad hoc committee; no provisions on budgeting and financing of the Baltic Assembly had been included, etc.
The members of the Baltic Assembly (BA) Legal Committee recognised the deficiencies of the Regulations; therefore, at the 12th Session on May 8-9, 1998, Daimar Liiv, a member of the Legal Committee and member of the Estonian delegation to the Baltic Assembly, proposed that new Statutes of the Baltic Assembly should be drafted before its 13th Session. The drafting was started, but it took longer than expected. The draft of the Baltic Assembly Statutes had to be examined not only by the BA Legal Committee but also by the Legal Departments of the Estonian, Latvian and Lithuanian parliaments and ministries of justice. The Statutes of the Baltic Assembly were finally adopted at the 14th Session on May 29, 1999, in Vilnius. They replaced the Regulations of the Baltic Assembly, which were made null and void. Amendments to Article 54, Paragraph 1, of the Baltic Assembly Statutes were made at the 16th Session on May 27, 2000, in Tartu, to regulate finances of the Baltic Assembly.
The BA Statutes were adopted on 29 May 1999. The consolidated text of the Statutes contains the amendments adopted on 27 May 2000, 14 December 2002, 29 November 2003, 19 December 2004, 22 October 2010, and 25 November 2011.
The Statutes of the Baltic Assembly consist of 6 chapters and 49 articles that regulate the basic activities of the Baltic Assembly, the work of its bodies, the procedure for preparing BA documents, and cooperation with the Baltic Council of Ministers.
