Each question consists of legal propositions/ principles (hereinafter referred to as 'principle') and facts. These principles have to be applied to the given facts to arrive at the most reasonable conclusion. Such principles may or may not be true in the real sense, yet you have to conclusively assume them to be true for the purposes of this section. In other words, in answering the following questions, you must not rely on any principles except the principles that are given herein below for every question. Further, you must not assume any facts other than those stated in the question. The objective of this section is to test your interest towards study of law, research aptitude and problem solving ability even if the 'most reasonable conclusion' arrived at may be unacceptable for any other reason. It is not the object of this section to test your knowledge of law.

PRINCIPLE: Ignorance of law excuses no one.

FACTS: 'X' fails to file his income tax returns for a considerable number of years. The Income Tax department serves upon him a 'show-cause notice' as to why proceedings should not be initiated against him for the recovery of the income tax due from him with interest and penalty.

Which of the following derivations is CORRECT?

The correct answer is: 'X' would have to pay the due, as ignorance of law and failure to comply with law is no legal ground of defence.

Let us carefully analyze the principle and the facts, and then evaluate each option to arrive at the most reasonable conclusion.

Understanding the Principle:
The principle stated is: "Ignorance of law excuses no one."
This is one of the most fundamental maxims in jurisprudence, often expressed in Latin as ignorantia juris non excusat. It means that a person cannot escape legal liability simply by claiming they did not know a particular law existed or applied to them. Every person is presumed to know the law of the land.

Understanding the Facts:
'X' failed to file his income tax returns for a considerable number of years. The Income Tax department has issued him a show-cause notice asking why proceedings for recovery of tax, interest, and penalty should not be initiated against him.

Evaluating each option:

Option 1: 'X' may defend himself by taking the plea that his legal advisor had not advised him to file the return.
This is incorrect. The principle makes no distinction between personal ignorance and ignorance caused by reliance on a third party (like a legal advisor). The law presumes that every individual is responsible for knowing and complying with it. Blaming a legal advisor does not dissolve 'X's own legal obligation to file returns. The duty to comply with tax law rests on 'X' personally.

Option 2: 'X' would have to pay the due, as ignorance of law and failure to comply with law is no legal ground of defence.
This is correct. Directly applying the principle — "ignorance of law excuses no one" — 'X' cannot plead ignorance to escape his liability. He was legally obligated to file income tax returns, and his failure to do so over a considerable number of years makes him liable for the tax due, along with interest and penalties. No matter what reason 'X' offers, if it amounts to saying "I did not know," it cannot serve as a valid legal defence under this principle.

Option 3: 'X' may defend himself successfully by taking the plea that he was unaware of any such law being in force.
This is incorrect. This option is a direct restatement of the very kind of plea that the principle prohibits. Claiming unawareness of a law being in force is the classic example of ignorance of law, and the principle explicitly states this excuses no one. Such a plea would not succeed.

Option 4: None of the above.
This is incorrect, since Option 2 is clearly the correct and most reasonable conclusion derivable from the given principle and facts.

Conclusion:
By applying the principle "Ignorance of law excuses no one" to the facts, it is clear that 'X' cannot use his ignorance — whether personal or attributed to his advisor — as a shield against legal proceedings. He is legally obligated to pay the income tax due along with applicable interest and penalty. Therefore, Option 2 is the correct derivation.
