No amount of validation changes a theory into a law. Scientific laws and scientific theories are two different things used for different purposes.

The scientific community isn't casting doubt on a theory by labeling it as such, and a scientific theory isn't some middle step were a scientific idea has to be milled about before graduating to scientific law.

Scientific theories are, above all, tools for scientific research. They more successful they are in making accurate predictions and framing scientific data, the more accepted they are. In other words, if they are useful and accurate, they stick.
