The law often has been described as “a seamless web” in which principles are hopelessly and endlessly intertwined. However, there are ways to classify legal subjects that advance understanding of the law and legal principles.
Public LawandPrivate Law
Public lawincludes constitutional law, administrative law and criminal law.
Constitutional lawinvolves the interpretation and application of either the federal or a state constitution.
Administrative lawdescribes the legal principles that apply to government agencies, bureaus, boards, and commissions.
Criminal lawencompasses all legal aspects of crime. In each of these areas, society, or “the people”, are directly involved in the issues. Their interests are represented by a governmental agency, officer, or official whose obligation is to see that justice is accomplished and the ends of society achieved.
Public law provides a major portion of the legal environment of business.
Private lawencompasses those legal problems and relationships that exist between individuals, as contrasted with those in which society is involved. Private law is traditionally separated into the law of contracts, the law of torts, and the law of property. Contract law addresses agreements between two parties. Tort law addresses wrongs other than a breach of contract, by which one party injures another. Property law deals with all aspects of ownership and possession of both tangible things and intangible rights.
Our whole economic system is based upon the rights of individuals to acquire and use private property
Subdivision of the classifications of legal subjects:
The Law of Contracts: sales of goods, commercial paper, secured transactions,bank deposits and collections, creditor’s rights, consumer protection
The Law of Torts:assault and battery,slander and libel, invasion of privacy, interference with contracts, negligence, conversion, products liability
The Law of Property: real property, personal property, leases, bailments, wills, trusts and estates, mortgages.
Civil Law and Criminal Law
Another means of classifying the law is to divide it into civil law and criminal law. For administrative purposes, courts usually separate criminal actions from all other lawsuits. Civil cases may include suits for breach of contract or tort cases, such as suits for personal injuries. Typically, they involve a request for damages or other appropriate relief that does not involve punishment of the wrongdoer.
Substantive Law and Procedural Law
Another important classification or distinction in law is between substance and procedure.
Substantive law defines the legal relationship of people with other people or between them and the state. Thus, the rules of contract law are substantive.
Procedural law deals with the method and means by which substantive law is made and administered. In other words, substantive rules of law define rights and duties, while procedural rules of law provide the machinery for enforcing those rights and duties. Every social institution has rules by which it conducts its affairs, or “proceeds”. Rules of law relating to legislative procedure govern the steps that must be taken for a statute to be valid – that all bills be read to the assembly twice before voting, for example. Failure to follow the rules of procedure might void the legislature’s attempt to create rights or duties. Judicial procedures involve the conduct of lawsuits and appeals and the enforcement of judgments. The rules for conducting civil trials are different from those for criminal trials. For example, each party may call the other party to the witness stand for cross-examination in a civil trial, but the defendant may not be required to testify in a criminal case. Procedural problems sometimes arise concerning papers filed in lawsuits, the admission of evidence, and various other techniques involved in trying the case. They are the rule’s of the game.
SOURCES OF LAW
The total body of law by which we are governed comes from four basic sources:
Constitutions
Legislation
Judicial decisions
The rules, regulations, and decisions of administrative agencies, called administrative law.
