No, that's not what happened. The problem isn't simply that Antonopolous lacked credentials; it's that they disclosed him as a witness at the 11th hour without giving the court time to vet him. If you read the ruling, Steve Bellovin was also rejected, despite the judge's repeated acknowledgement of his outstanding credentials. In both cases, the defense was also unable or unwilling to describe what their expert witnesses would testify to, which they are required to do, just as the prosecution was required to do the same for their witnesses, to allow the opposing side time to prepare.
