Explain the International law

International law is the body which governs State actions and its effective implementation within the States depends on the way in which States treat their international law obligations within their own domestic legal systems, thus, depending on the nature of their relationship between international  law  and  municipal  law.  There  are  two  schools  of  thoughts  describing  the relationship between International law and municipal law: monism and dualism. According to monism, municipal law and international law are part of a universal legal order, with international law being part of the same system. Whereas, dualists states that there are two distinct systems of law each having its own sphere of application.
