Investigators seeking to question him on allegations of insurrection have struggled to execute a warrant for his arrest.
The head of the investigation unit, blocked by a human chain of hundreds of presidential security service and military guards outside his residence last week, said earlier on Tuesday they remained determined to bring him in.
Yoon's lawyers filed an injunction request to a Seoul court to nullify the arrest warrant, but the court struck that down on Sunday, a court official said on Tuesday.
