Can SMS be used as evidence in court?: "SHAH ALAM: The High Court will decide on Dec 7 whether to allow as evidence the SMS and phone calls made by Tengku Teh Susilawati Tengku Akhirat to her sister Tengku Teh Suhira.
Deputy Public Prosecutor Salehuddin Saidin said the SMS and calls should not be regarded as hearsay.
Last week, defence counsel G. Subramaniam Nair, in his submission, said they should not be admissible. "
