I need some assistance with these assignment. the role of judges in making law in uk courts Thank you in advance for the help! This principle of precedent is also known as 'stare decisis'. This precedent should be created by a high ranking court and not from the courts of first instance. They are supposed to follow strictly the already existing law and precedents. Often these courts would be engaged in fact finding since they are not expected to hear full legal arguments of the parties. The courts administration documents and reports the decisions from 1865 in U.K. It is called now Incorporated Council of Law Reporting for England and Wales. It brings out The Weekly Law Reports and The Law Reports. The decisions that are taken as legal precedents shall have 'ratio decidendi' behind them. The ratio decidendi must be related to the law and not on factual findings. It can not also be 'obiter dictum' mentioned as a passing reference while deciding the case and shall have no legal basis for future decisions. The ratio which is binding shall have legal principles and rules considered for finding a solution for the problem in the case. The 'obiter dicta' however are treated as persuasive authority which later judges can use them for arriving at their decisions but are not bound to treat them as precedents.(UK law online)

Precedent has a very important role in the common law. It ensures certainty and consistency and logical progression and development in the law. At the same time it can be rigid and also complex - what is "the law" on a subject may be very difficult to find or to state as it is spread across many cases. So, many countries (especially in Continental Europe) prefer a codified system in which laws are set out in legislation and cases which apply them may be illustrative but do not become binding. The law is also easier to find and to state and is rationally prospective rather than based on the chance event of litigation, which may give rise to laws based on extreme or unusual situations or unevenly argued cases. For example, here is the offence of murder in US Federal Law. By contrast, the law of murder in England is contained in several cases, and even having read them there may be room for doubt. As for English law, the classic definition of murder is considered to be that given by Lord Chief Justice Coke who (writing in the early seventeenth century) said: "Murder is when a man of sound memory and of the age of discretion, unlawfully killeth within any county of the realm any reasonable creature in rerum natura under the King's peace, with malice aforethought, either expressed by the party or implied by law, so as the party wo, or hurt etc. die of the wound or hurt etc .within a year and a day of the same." (UK Law online)

Blackstone stated in eighteenth century that court decisions were mere evidence of common law.
