Observing that threat and intimidation were major causes for witnesses turning hostile, it said when the witnesses are not able to depose correctly before the court, it results in low conviction rate and many times even hardened criminals escape the conviction.
"It shakes public confidence in the criminal justice delivery system," a bench of justices A K Sikri and Amitava Roy said.
The bench noted in its verdict that it has become a common phenomenon and almost a regular feature that in criminal cases witnesses turn hostile.
The court's observation came while dismissing an appeal filed by four persons, who were convicted by the Punjab and Haryana High Court for the offences of murder and subjecting a married woman to cruelty.
The husband and in-laws of the deceased woman had moved the apex court challenging the high court's judgement, saying there was no reason to rely on the dying declaration as there were certain infirmities in it.

The police had alleged that the husband and in-laws of the victim were subjecting her to cruelty for dowry and when she was sleeping at her home, the accused poured kerosene on her and set her ablaze.
The apex court also agreed with the views of the high court that the brother of the deceased appeared to have been won over by the accused.
"Present case appears to have been stung by 'culture of compromise'. Fortunately, statement of PW-4 (brother of the deceased) in attempting to shield the accused (husband of the deceased) has been proved to be false in view of the records of PGIMS, Rohtak and, therefore, we held that the high court was right in discarding his testimony," the bench said.
