The Attorney-General's Chambers says it has not decided whether it will appeal the not-guilty verdict of former top cop Ng Boon Gay.
A spokesman said: "We will assess the grounds of decision and assess whether to appeal or not".
Similarly, the prosecution will have to decide whether or not to charge star witness Cecilia Sue, 36.
Mr Ng, 46, the former head of the Central Narcotics Bureau, was found not guilty by District Judge Siva Shanmugam on Thursday afternoon.
He was accused of obtaining four counts of oral sex from Ms Sue in 2011, in exchange for furthering the business interests of her then employers, Hitachi Data Systems and Oracle Corporation Singapore.
Mr Ng's lawyer, Mr Tan Chee Meng, said they are "extremely happy with the outcome".
Mr Ng's wife, Madam Yap Yen Yen, was crying and holding a relative's hand when the judgment was being read out and when the judge accepted her husband's testimony to be true. Mr Ng looked calm.
Asked later if it was the best Valentine's Day present she had received, she nodded and smiled.
In his verdict, the judge said he found no ulterior motive or corrupt intent in what Ng did. He said both Mr Ng and Ms Sue's intentions were "innocuous", and that there was no reason to believe that her offer of oral sex was intended as an act of inducement.
Mr Ng could have been jailed up to five years and fined up to $100,000 for each of the four charges.
Mr Tan, who had put up a strong defence of Mr Ng, said it had been a tough year for his client and the latter wanted to extend his heartfelt gratitude to people who have supported him, including strangers.
