Irrelavent question in Cross Examination

First, the party that called the witness examines him, this process is called examination-in-chief as mentioned under Section 137 of the Evidence Act.

After the completion of the examination-in-chief, if the opposite party wants to, they can take over the witness and cross-question him about his previous answers.

The opposite party may ask him any question regarding all the relevant facts and not merely the facts discussed during examination-in-chief. This process has been described in Section 137 of the act as cross-examination. If the party that called the witness sees the need to examine the witness again after cross-examination, they may examine the witness one more time. This has been laid down as re-examination in Section 137 of the Indian Evidence Act, 1872.

In cross examination opposite party or his counsel may ask any and many questions regarding case but can't ask beyond pleadings and subject matter of case.
