Justice Nutan Sardesai dismissed the petition filed by Tejpal, who is accused of raping the woman during an event in Goa in 2013.
The detailed order is expected to be pronounced later in the day.
The district court in Mapusa town had earlier framed charges against Tejpal under IPC sections 354-A (sexual harassment), 376 (rape) and 376(2)(k) (rape of a woman by a person being in tge position of control or dominance over the woman), and initiated a trial last month.
"The detailed copy of the order, by which our petition has been dismissed, is not with us so we are not able to know on which ground it was rejected," lawyer Pramodkumar Dubey, who represented Tejpal in the high court, told PTI.
Public prosecutor Saresh Lotlikar earlier said the trial court (district court) had come to the conclusion that a "primary case" had been made out as charges had been framed.
He said the charges against the accused should not be dismissed without a trial in the case.
