> A judge is supposed to read the smart contract source code and determine the intent?

If necessary, they can call on experts to provide testimony in such cases. It's probably not necessary all that often though because there's usually more relevant auxillary information to help work this stuff out. Who wrote this smart contract? Why are the parties using it? What information persuaded them to use it? Was the outcome of using the smart contract different to what a reasonable person would have expected?

This is exactly what courts are for! The fact that some of the procedure of the interaction has been mechanised does not mean the participants get to ignore the law.
