Section 128B(2) in The Motor Vehicles Act, 1939
(2) A person while at a hospital as an indoor patient may be required by a police officer to provide at the hospital a specimen of his blood or urine for a laboratory test-
if it appears to the police officer that the device by means of which test is carried out in relation to the breath of such person indicates the presence of alcohol in the blood of such person, or
' if that person having been required, whether, at the hospital or elsewhere, to provide a specimen of breath for a breath test, has refused, omitted or failed to do so and a police officer has reasonable cause to suspect him of having alcohol in his blood: Provided that a person shall not be required to provide a speci- men of his blood or urine for a laboratory test under this sub- section if the registered medical practitioner in immediate charge of his case is not first notified of the proposal to make the requirement or ob- jects to the provision of such specimen on the ground that its provi- sion or the requirement to provide it would be prejudicial to the proper care or treatment of the patient.
