Section 132 requires a witness to answer relevant questions in civil or criminal proceedings even where an answer may incriminate the witness or expose the witness to a penalty or forfeiture. A compelled answer cannot subject the witness to arrest or prosecution, nor may it be proved against the witness in criminal proceedings, except in a prosecution for giving false evidence through that answer.

Section 131 prevents compelled production of documents or electronic records held by one person when another person could lawfully refuse their production if they held or controlled them. Production may be compelled only where the person entitled to refuse consents, preserving the underlying protection despite the material being in another person's possession or control.

Section 130 protects a non-party witness from compulsory production of title deeds, documents evidencing property held as pledgee or mortgagee, and documents that may tend to incriminate the witness. Production may be compelled only where the witness has agreed in writing with the person seeking production, or a person through whom that person claims, to produce them.

Confidential communications with a legal professional adviser cannot ordinarily be compelled before a court. Where a person offers himself or herself as a witness, disclosure may be required only for communications necessary to explain evidence already given. Other confidential communications remain protected.

Reassessment proceedings initiated through a notice and an authorising order under Section 148A(d) fell outside the applicable statutory limitation period. Under the governing principle for reassessment limitation, both the notice and the Section 148A(d) order were invalid as time-barred. As limitation disposed of the validity issue, separate examination of other challenges was unnecessary.

Legal professional privilege is not waived merely because a party gives evidence voluntarily or otherwise. Giving evidence does not constitute consent to disclosure of protected matters. Where a party calls a barrister, pleader, attorney or vakil as a witness, consent is implied only to the extent that the party questions the legal professional about matters which would otherwise remain protected from disclosure.

Professional communications confidentiality extends to interpreters and to clerks or servants of barristers, pleaders, attorneys and vakils. They are subject to the same restrictions governing privileged communications with legal advisers.

Professional communications privilege bars disclosure, without the client's express consent, of employment-related client communications, documents encountered professionally, and legal advice. The obligation continues after employment ends. Privilege does not protect communications made to further an illegal purpose or facts observed during employment showing a crime or fraud committed after employment began. A request for defence regarding a past offence remains protected, but using a forged instrument to obtain property and observed subsequent fraudulent alterations are outside the privilege.

Confidentiality of offence-information sources protects Magistrates and police officers from compelled disclosure of the source of information concerning any offence. Revenue officers receive the same protection for information relating to offences against public revenue, and include officers employed in or connected with any branch of public revenue.

Section 124 protects official communications made to public officers in official confidence from compelled disclosure where the officer considers that disclosure would injure public interests. It bars compulsion to disclose such confidential official communications, subject to the officer's assessment of potential public-interest harm.

Evidence derived from unpublished official records concerning affairs of State cannot be given unless permission is obtained from the officer heading the relevant department. The departmental head may grant or withhold permission at discretion, thereby regulating disclosure and evidentiary use of State-related material held in unpublished official records, including material maintained in official departmental custody and linked to governmental affairs.

Marital communications cannot be compelled from a current or former spouse and cannot be voluntarily disclosed without the communicator's consent or that of the communicator's representative in interest. The protection is excluded in proceedings between married persons and in prosecutions concerning a crime committed by one spouse against the other.

Judges and Magistrates cannot be compelled to answer questions about their judicial conduct or matters learned in court while acting in that capacity, unless a subordinate court issues a special order. They may, however, be examined regarding other events that occurred in their presence while acting judicially. Questions concerning an allegedly improper deposition or statements made before a Magistrate require a superior court's special order.

In every civil proceeding, each party to the suit and the husband or wife of any party is competent to testify. In criminal proceedings against a person, that person's husband or wife is likewise competent to testify. The rule treats marital status as no bar to competency in these proceedings.

A witness unable to speak may give intelligible evidence through writing or signs made in open court, which is deemed oral evidence. Where the witness cannot communicate verbally, the court must take assistance from an interpreter or special educator in recording the statement and ensure that the statement is videographed.

Competency to testify extends to all persons unless tender years, extreme old age, bodily or mental disease, or a comparable cause prevents understanding questions or giving rational answers. Mental illness alone does not disqualify a witness; disqualification depends on impaired comprehension and inability to respond rationally.

GST treatment classifies food supplied by cloud and central kitchens as restaurant service taxable at 5% without input tax credit, while pre-manufactured ice cream sold without preparation is goods taxable at 18%. Government-funded disability-scheme coaching and toll overloading charges receive the applicable exemptions, and qualifying vehicle rentals are treated as giving on hire. Mineral exploration and mining rights, specified amusement admissions, and alcoholic-liquor job work are subject to 18% treatment in the stated circumstances, while qualifying overseas satellite launch services are zero-rated exports.

Section 117 creates an estoppel preventing an acceptor of a bill of exchange from disputing the drawer's authority to draw or endorse the bill. A bailee or licensee cannot deny the bailor's or licensor's authority at the commencement of the bailment or licence. An acceptor may challenge the purported drawer's genuineness, while a bailee may prove another person's superior right to delivered goods.

Tenant and licensee estoppel prevents a tenant, or a person claiming through the tenant, from disputing the landlord's title to immovable property at the beginning of the tenancy while it continues. It also prevents a person who entered property under a licence from denying the licensor's title to possession when the licence was granted.
