Key words: Banach lattices, Hahn–Banach Theorem, odered vector spaces, regular operators. 1. Some Deﬁnitions and Notations An ordered vector space F has the Riesz decomposition property (RDP in short) if for any positive elements z, x ,x with z x + x , there exist z ,z such that 1 2 1 2 1 2 0 z x , 0 z x and z = z + z . The RDP is equivalent with the 1 1 2 2 1 2 ﬁnite interpolation property, i.e., if x ,x z ,z then there exists y such that 1 2 1 2 x ,x y z ,z (, p. 129). Every Riesz space has the Riesz decomposition 1 2 1 2 property, but the
