The procedure in the inquisitorial system is essentially written. Most witnesses testified at the investigative stage, and this evidence is included in the record in the form of police reports. Similarly, the accused has already taken his case to the investigation stage, but he is free to change his testimony at trial. Whether the defendant pleads guilty or not, a trial will take place. Unlike the adversarial system, the conviction and sentence to be served (if any) are pronounced by the jury and the Presiding Judge after joint deliberation. The common law is more malleable than statutory law. First, common law courts are not absolutely bound by precedent, but can (if extraordinarily good reasons are demonstrated) reinterpret and revise the law without legislative intervention to accommodate new trends in political, legal and social philosophy. Second, the common law evolves through a series of step-by-step steps that progressively work out all the details, allowing the law to change significantly over a decade or more, but without a clean break, thereby reducing disruptive effects.  Unlike the incrementality of the common law, the legislative process is very difficult to put in place, as legislators tend to delay action until a situation is intolerable.
For these reasons, legislative changes are usually significant, painful and disruptive (sometimes positive, sometimes negative and sometimes with unintended consequences). Scotland shares the Supreme Court with England, Wales and Northern Ireland for civil matters; Court decisions are binding on the court from which a case arises, but only concern similar cases in Scotland. This has led to a convergence of law in some areas. For example, modern British negligence law is based on Donoghue v Stevenson, a case that originated in Paisley, Scotland. The common law defines that if a couple lives together for a certain period of time (varies by state) and claims to be married to their community, it can be considered as such. In other words, you and your spouse don`t have to go through legal channels to get a marriage license to be considered a married couple for inheritance purposes and other potential legal issues. Many churches use a system of canon law. The canon law of the Catholic Church influenced common law in the Middle Ages by preserving Roman jurisprudence such as the presumption of innocence.  Nevertheless, the lower courts have the power to depart from precedents if the judge finds that they are outdated or not applicable to this case. A common law subordinate court may also set a precedent in rare cases. The common law – so called because it was “common” to all the royal courts of England – has its origins in the practices of the courts of English kings in the centuries following the Norman conquest in 1066.  The British Empire then extended the English legal system to its remote colonies, many of which retain the common law system today.
These “common law systems” are legal systems that attach great importance to case law and the style of reasoning inherited from the English legal system.     The investigating judge then submits the file with his conclusions to the President of the Chamber, who decides on the case in which it was decided that the proceedings should be conducted. Therefore, the view of the President of the Chamber on the case is not neutral and may be biased in the conduct of the proceedings after reading the file. Unlike common law procedures, in the Inquisition system, the presiding judge is not only an arbitrator and has the right to examine witnesses directly during the trial or to comment, as long as he does not comment on the guilt of the accused. The common law forms the basis of the legal systems of: Black`s Law Dictionary 10th Ed., Definition 4, distinguishes “common law” (or simply “law”) from “equity”.    Prior to 1873, England had two complementary judicial systems: the courts of “justice”, which could only award pecuniary damages and recognized only the rightful owner of the property, and the courts of “equity” (courts of chancery), which could issue injunctive relief (i.e. an order of the court to a party to do something, to give something to someone or refrain from doing something) and recognized property trusts. This split spread to many colonies, including the United States. The states of Delaware, Mississippi, South Carolina and Tennessee continue to have courts of law and chancery courts. In New Jersey, the courts of appeals are united, but the trial courts are organized into a division of chancery and a division of law.
