Section 250 of the Income Tax Act

Delay in filing appeals, when supported by sufficient or justifiable cause, should be condoned with a liberal approach to ensure substantial justice. This principle prioritizes the cause of justice over mere technicalities.

When two equally plausible interpretations of a taxing provision are possible, or when conflicting views exist from non-jurisdictional High Courts, the interpretation that favors the assessee must be adopted.

A penalty notice issued under section 274 read with section 271(1)(c) is invalid if it fails to specify whether the penalty proceedings are initiated for concealment of income or for furnishing inaccurate particulars of income. This non-specification vitiates the penalty proceedings.

An appeal before the Income Tax Appellate Tribunal can be dismissed for non-prosecution or treated as unadmitted when the appellant fails to appear, cooperate, or show diligence, in accordance with Rule 19(2) of the Income-tax (Appellate Tribunal) Rules. The law aids the vigilant, not those who sleep on their rights.

Penalty under Section 271(1)(c) for furnishing inaccurate particulars or concealment of income is not automatically leviable if the assessee has made a full disclosure of all particulars and the addition or disallowance arises from a difference of opinion.

A court or tribunal is not bound to answer a reference or adjudicate an appeal on its merits if the party at whose instance the proceeding is made fails to appear at the hearing or take necessary steps for its proper conduct.

An assessee cannot raise a new claim or a claim not made in the original or revised return of income for the first time directly before the Assessing Officer during assessment proceedings.

Late fees under section 234E are not applicable for periods prior to June 1, 2015, as the amendment to section 200A inserting clause (c) was effective from that date.

The principle of consistency applies in tax matters, meaning a fundamental aspect found to be true in one assessment year should not be changed in a subsequent year if the order was not challenged.

Appealing a tax assessment requires more than just filing the appeal; it involves actively pursuing it. The assessee must effectively engage with the appellate process.
