"Due diligence" is the diligence (= carefulness) that you should exert before signing on the deal. Don't trust what the other side tells you. Instead, check.

"Due process" is the legal steps that have to be followed in a court case (especially a criminal one). You can waive due process - if you're not going to make the government work through all the steps, because you know that it's not going to get you any benefit in the end, say.

Musk waived due diligence, not due process.
