Double relativity is grounded on both, the theory of special relativity and the definition of speed as the ratio of a distance to the time it takes a body to traverse it, even if that distance is in relative motion with respect to the frame where both magnitudes are measured. This paper proves double relativity and special relativity lead to a contradiction involving the speed of light in a vacuum. It, then, proposes two alternatives to solve the inconsistency.
