"We are of course bound by the Constitutional Court verdict, but I don't have to respect it," said the premier, a day after the US-based social media site went live again in Turkey.
"I don't respect this ruling."
Erdogan's government has been rattled by the twin crises of street protests since last June and, since December, a torrent of on line leaks on Twitter, Facebook and YouTube which appeared to implicate the premier's inner circle in corruption.
YouTube remains banned since it was also used to leak an audio recording that was purportedly of a conversation of top government, military and spy officials weighing possible military action inside neighbouring war-torn Syria.
"All our national, moral values have been put aside," he said about the spate of anonymously posted recordings."Insults to a country's prime minister and ministers are all around."
The Internet crackdown has sparked protests from Turkey's NATO allies and human rights groups, who have deplored it as curbing the right to free speech -- a notion Erdogan dismissed.
"This is a commercial company which has a product," he said of the San Francisco-based micro-blogging service.
