A tuple of commuting contractions T=(T 1 , T 2 , ..., T n ) is called a joint-isometry if T\* j T j =I. We give a geometric proof that joint isometries have a regular unitary dilation and that its commutant lifts. We also show that T is subnormal and that its minimal normal extension is also jointly
