Removing arrays which contain duplicate elements in Numpy

Question

Suppose I have an array like so:

[[0, 1, 2, 3]
 [2, 3, 3, 4]
 [4, 3, 2, 1]
 [1, 1, 2, 3]]

I need to remove all rows containing duplicate elements, to obtain:

[[0, 1, 2, 3]
 [4, 3, 2, 1]]

I'm thinking there's a way to do this with advanced indexing, but show me whichever way is most efficient.
