Experts feel the abortion law could be changed to make those seeking abortion think harder and longer. Part of the aim of legalising abortion then was to safeguard the health and well-being of women. SMU Associate Professor of Law Tan Seow Hon, who has written several papers on abortion and also teaches legal philosophy which covers the parliamentary debates that led to the current laws, said the reasons for allowing abortion then should be relooked. She said stricter abortion laws would lead people to be more circumspect about unprotected sex, not drive them to backstreet abortionists. "The ratio of the high number of abortions to the number of live births says something about a cavalier attitude towards the worth of the unborn," she said. "We should ask whether liberal abortion laws have played a part in enabling people to make choices about sex without protection, knowing that they would have easy legal access to abortion anyway. It does not seem likely that in the majority of instances of abortion, contraception was used and failed."
