Natural law does not have any precise definition, it is known as the law of reasons or the ethical or the moral law. It is not made by man, it is only discovered by him. It emanates from human reasoning and it appeals to it only, it does not need any sort of compulsion to be implemented as the principles of natural school or law are embodied in the human consciousness itself. It can be regarded as a way of looking at things in the quest of ensuring justice.[1] Though it is said to be developed by Greek philosophers, but in actuality it was there present in the nature itself from the time immemorial.[2] The greatest contribution of natural law theory to the legal system is its ideology of a universal order governing all men and the inalienable right of individuals[3]

The concept of natural law has greatly contributed to the development of many laws in the contemporary scenario or it can be stated with profound surety that any law which violate the principles of natural law does not stand much in a democratic society. The concept of Rule of Law� in India and England and the concept of due process� in the USA had been emanated from this School only.

But our concern here would be the Impact of Natural Law on the Indian Penal Code. The validity of Natural Law school derives from its own inherent values, differentiated by its living and organic properties from the law promulgated in advance by the State itself or through its agencies furthermore the greatest attribute of the natural law theory is its adaptability to meet new challenges of the transient society.[4]

IPC is nothing else than the codification of the Negative Human desires, which are very natural in their origin but when manifested becomes a punishable offence. Though there are many other provisions but in this short Article the authors particularly emphasis on Mens-Rea, Right to Private Defence, Defence of Necessity and Section 377.

Mens-Rea
For constituting any criminal offence or crime the two of its essentials are Mens-rea and Actus-reas[5]. Mens-rea is the mental element or the guilty intention and actus-reus is the willful act done in cognizance of that intention (mens-rea). The concept of Mens Rea as constituting the basic element of crime has been recognized by the maxim Actus non facit reum nisi mens sit rea�[6]which means that the person cannot be guilty unless he has a guilty mind.

In my understanding the due importance given to intention is because of the fact that human beings have the power of reason and somehow reasons do dictate the actions of the people. It would be justified to punish a person whose mind is guilty and he goes on to do an offence in furtherance of that guilty mind. But punishing someone without taking his mental element into consideration would be wholly unjustified. This whole thinking is nothing else than the impact of Natural law, where due emphasis is given to equity, justice and good conscience and where the reasons of the person has been taken into consideration. Natural law is the criterion which permits to evaluate positive law and to measure its intrinsic justice.[7]

Right to Private Defence
The right to private defence has been embodied under section 96 to 106 of the Indian Penal Code[8]. In the case of Laxman v State of Orissa[9] it was held that right to private defence is available to every person when there is an unlawful aggression against the life and property of the person. The reason for this is none other than the basic principle of Natural law according to which every person has a right to protect oneself and his own property in case of danger; law does not want the person to behave like a coward.

He can take the law into his hands and can go to the extent of causing death of the aggressor in case if the imminent danger which is threatening his own life. The cardinal principal and the whole idea of providing right to private defence as a General Defence as which would be justified in the eyes of law and would not be a punishable offence was the thinking based on the natural instinct of a man in case of danger.

There is a practical ground also which justifies this right; the primary duty of state is to protect its citizens but because of the paucity of resourses it is impossible for the state to provide security to each and every human being, therefore the concept of natural and ingrained rights of defence come into picture.[10]

Defence of Necessity
The defence of Necessity has been embodied under section 81 of the Indian Penal Code. It justifies the act of the person and exonerates his liability under situations in which the act of the person was done because of necessity and in order to prevent some greater harm and when the said act was done without any criminal intention and in good faith.[11]


Under grave and sudden circumstances which this defence of necessity harbingers; the human nature is bound to act in a spontaneous fashion which would be without any pre-mediation or pre-planning; meaning to say that which would signify the naturality of the act done by the person.

The Act of the human being would always be based on the natural and basic instinct of the human being which is to act by the conscience and to do minimize the dangerous consequences of his act. The following illustration would explain the relation which we are trying to indicate; A in order to stop fire from spreading pulls down the houses in order to save human life and property, if it is found that he did this in good faith and without and criminal intention; and in order to prevent some greater harm then he would be exonerated from the liability.

The defence of necessity is based on the premises of two Latin maxims: quod necessitas non habit leegem (means: necessity knows no law) and necessitas vincit legem (means: necessity overcomes the law[12]. These two maxims justifies the role of natural law in the codification of the defence of necessity as the study of natural law tends to motivate the citizens to engage in activities that express virtues and refrain from actions that express vices. Moreover in words of Aristotle� justice behest that a person should be guided by reason and refrain from indulging in acts which are unjust, unlawful and unfair and defence of necessity when proved neither falls within unjust, unlawful or unlawful unfair category of acts.

Section 377
This section was embodied in the IPC to make carnal intercourse punishable which is against the order of nature, as the legislators at that time thought; for example intercourse between man and man or between woman and woman or between man and woman with any animal. This would amount to a punishable offence under this section and the punishment would extent to 10 years imprisonment and fine.

This section was criticized on the grounds that it makes consensual sexual intercourse between two consenting adults a punishable offence; and this is tantamount to the violation of their life, privacy, dignity, identity and their liberty to have their own sexual orientation of their choice; and ultimately because of the violation of so many Natural rights of the person this section was ultimately decriminalized by the Supreme Court in 2018; as the court came to the conclusion that sexual orientation embodies into the natural personality of the person and punishing the same would tantamount to the violation of his or her natural right.

Brief journey of the section which ultimately led to its unconstitutionality:
Petitions for checking the validity of the section was filed in the Delhi High court in 2009.

In Naz foundation v NCT Delhi[13] The Hon'ble High Court of Delhi held that section 377 is unconstitutional as it criminalizes consensual sexual intercourse between two adults in their privacy and which is a violation of Article 14, 15 and 21. This judgement of the high court never saw the light of the day as it was stayed by the Supreme Court.[14]

But ultimately after the judgement of NALSA v Union of India[15] and Puttaswamy[16] case the background for its unconstitutionality was ready. Also in Navtej Singh Johar v Union of India[17] the 5 judge's constitutional bench of the Supreme Court declared section 377 as partially unconstitutional; as far as it criminalizes consensual sexual intercourse between two adults. The court applied the Natural school of jurisprudence for striking down the section partially.

The Right of Privacy of the person is of supreme importance and the right to choose one's is very fundamental to the right to life; and the court further emphasized that the sex of the person also includes his or her sexual orientation also.

Natural law school cannot be regarded as a body of actual enacted or interpreted law enforced by courts but it is much far beyond this whereas it is a way of looking at things and a humanistic approach of judges and jurists.[18] Within itself it embodies a host of conceptions such as justice, reason, good conduct, freedom, equality, liberty, ethics, morality, and so on. This was the reasoning of the court; by giving due importance to the natural ingrained right to life, liberty and choice the court partially struck down the provision of the IPC which was not in consonance with the Natural Law; so deep is the impact of Natural Jurisprudence on IPC.

Conclusion
In short it can be stated that the impact of natural law is immense not only on the IPC but also on any codified law of a democratic nation. Natural law embodies in itself justice, equity, good conscience. It is a law which deals with morality and reasons of the person; and any Law would lose its sanctity if it is not accepted by the people; and anything contradictory to the general people's consciousness, morality and reason would never be accepted.

Therefore while making any law it is very important to take into consideration the natural school of jurisprudence. Natural Law theory reflects a perpetual quest for absolute justice; it is basically a priori method different from empirical method as it accepts things or conclusions in relation to subject as they are without any need or enquiry while empirical approach tries to find out the causes and reasons in relation to the subject- matter.

The essence of Criminal Law is IPC which is based on priori method whereas empirical method in Criminal law for ensuring justice is CrPC and evidence. Hence it could be rightly said that Natural Law has played a concrete role in framing our penal laws. The eternal lasting value of Natural law can be seen in IPC also as there are many other laws which are completely being repealed but the basic core element of an offence in the IPC is mens rea which can never be repealed; as IPC is nothing but a codification of the negative desire of the Human beings; and desires are the natural characteristic of a human, so to codify the criminality one has to look deep down into the fold of the naturality of our behavior and this cannot be done without the help of Natural School of Jurisprudence.
