The Supreme Court has asked search engines like Google India, Yahoo India and Microsoft Corporation India Pvt Ltd to respond to a PIL which alleged that they were violating laws and a court order by not blocking advertisements on sex determination of a foetus.<br/><br/>A bench of justices Dipak Misra and R. Banumathi yesterday said, such advertisements are in violation of Section 22 of the Pre-Conception and Pre-Natal Diagnostic Techniques Act. The court ordered if there is any such advertisement on any search engine, it shall be withdrawn immediately. The court instructed the search engines to file an affidavit in this regard within two weeks.
