Are expert reports admissIble into evidence without cross examination?

Sir,

From the Indian Criminal Justice System Point of view,

Reports of the officers envisaged under section 293(4) are admissible without cross examination along with any forensic or ballistic report by any government lab, as per judgement by the Hon'ble SC in H.P v. Mastram (2004) SCC, i dont remember the exact judgement though.

In most jurisdictions in the US, expert testimony is only admissible if both parties are given the opportunity to examine the expert witness, and thus only live testimony could be admitted.
