I came across an article that claims that 303 Creative v Elenis uses misleading information in its filing:
The Supreme Court is expected to deliver its opinion in a case in which Stewart plays a minor role [...] It took just a few minutes to reach him. I assumed at least some reporters over the years had contacted him about his website inquiry to 303 Creative—his contact information wasn’t redacted in the filing. But my call, he said, was “the very first time I’ve heard of it.”
Yes, that was his name, phone number, email address, and website on the inquiry form. But he never sent this form, he said, and at the time it was sent, he was married to a woman. “If somebody’s pulled my information, as some kind of supporting information or documentation, somebody’s falsified that,” Stewart explained.
The initial lawsuit did not mention the “Stewart” inquiry, which was submitted to Smith’s website on September 21, according to the date-stamp shown in later court filings, indicating that she received it the day after the suit was originally filed.
