Elon Musk is seeking to dismiss a lawsuit by US regulators alleging he wrongly saved money by revealing he increased his initial investment in Twitter too late.
The US Securities and Exchange Commission (SEC) said in a January complaint that Musk failed to disclose that he had built up his stake in the company within the regulator's timeframe.
It said this had allowed him to save about $150m (£123m) by purchasing shares in Twitter - which he bought outright months later and renamed X - at "artificially low prices".
Musk's lawyers, filing shortly before the court's deadline for his response, called the lawsuit "a waste of this Court's time and taxpayer resources".
"The SEC does not allege that Mr. Musk caused any investor harm. Rather, the SEC alleges that Mr. Musk late-filed a single beneficial ownership form three years ago, and fully corrected any alleged error immediately upon its discovery," they said in their Thursday filing.
