Legislation on the territorial sea.

At sea the Lithuanian State boundary is defined as passing along the line which limits its territorial sea, giving expression to the general rule that the sovereignty of the coastal State extends to the territorial sea. The breadth of the territorial sea of Lithuania is set at 12 nautical miles. The limits of the territorial area are measured from a straight baseline "connecting the two outermost points of the coast". A different limit of the territorial sea can be established by an international agreement of Lithuania. The Law on the State Boundary provides the general rules on the regime of navigation applicable to the Lithuanian territorial sea. To designate passage through the territorial sea the law uses the term "peaceful navigation" instead of the generally used "innocent passage".
