I'm curious to see where this goes. In my personal experience, it is standard practice to need/be requested to submit designs for review by a PE, if you aren't one. I was originally trained as a materials engineer, and nearly 20 years ago there was no clear PE exam to take for that discipline, so I never considered getting one. Today, I wouldn't want to be encumbered with the E&O insurance and other restrictions of a PE, and I would have to review extensively to pass the test. In my professional experience, it has always been nice to have a 3rd party look over your design, and the expense is of no consequence if the customer/law require the review. For a legal case, I'm not surprised that the barrier of entry for expert testimony might be a PE. I'd be interested to understand from a lawyer here on HN what the extent of protected speech is in a courtroom situation.
