An opinion is a judgment, viewpoint, or statement that is not conclusive, rather than facts, which are true statements.
A given opinion may deal with subjective matters in which there is no conclusive finding, or it may deal with facts which are sought to be disputed by the logical fallacy that one is entitled to their opinions.
Distinguishing fact from opinion is that facts are verifiable, i.e. can be agreed to by the consensus of experts. An example is: "United States of America was involved in the Vietnam War," versus "United States of America was right to get involved in the Vietnam War". An opinion may be supported by facts and principles, in which case it becomes an argument.
Different people may draw opposing conclusions (opinions) even if they agree on the same set of facts. Opinions rarely change without new arguments being presented. It can be reasoned that one opinion is better supported by the facts than another, by analyzing the supporting arguments. [1]
In casual use, the term opinion may be the result of a person's perspective, understanding, particular feelings, beliefs, and desires.
Though not hard fact, collective opinions or professional opinions are defined as meeting a higher standard to substantiate the opinion.

In contemporary usage, public opinion is the aggregate of individual attitudes or beliefs held by a population (e.g., a city, state, or country), while consumer opinion is the similar aggregate collected as part of marketing research (e.g., opinions of users of a particular product or service). Typically, because the process of gathering opinions from all individuals is difficult, expensive, or impossible to obtain, public opinion (or consumer opinion) is estimated using survey sampling (e.g., with a representative sample of a population).
In some social sciences, especially political science and psychology, group opinion refers to the aggregation of opinions collected from a group of subjects, such as members of a jury, legislature, committee, or other collective decision-making body. In these situations, researchers are often interested in questions related to social choice, conformity, and group polarization.
"Scientific opinion" may reflect opinions on scientific concerns as articulated by one or more scientists, published in scholarly journals or respected textbooks, both of which entail peer-review and rigorous professional editing. It may also refer to opinions published by professional, academic, or governmental organizations about scientific findings and their possible implications.
A related—but not identical—term, scientific consensus, is the prevailing view on a scientific topic within the scientific community, such as the scientific opinion on climate change.
Scientific opinion(s) can be "partial, temporally contingent, conflicting, and uncertain" [2] so that there may be no accepted consensus for a particular situation. In other circumstances, a particular scientific opinion may be at odds with consensus. [2]
Scientific literacy, also called public understanding of science, is an educational goal [3] concerned with providing the public with the necessary tools to benefit from scientific opinion.
A "legal opinion" or "closing opinion" is a type of professional opinion, usually contained in a formal legal-opinion letter, given by an attorney to a client or a third party. Most legal opinions are given in connection with business transactions. The opinion expresses the attorney's professional judgment regarding the legal aspect of the transaction. The opinion can be "clean" or "reasoned". [4] A legal opinion is not a guarantee that a court will reach any particular result. [5] However, a mistaken or incomplete legal opinion may be grounds for a professional malpractice claim against the attorney, pursuant to which the attorney may be required to pay the claimant damages incurred as a result of relying on the faulty opinion.
A "judicial opinion" or "opinion of the court" is an opinion of a judge or group of judges that accompanies and explains an order or ruling in a controversy before the court. A judicial opinion generally lays out the facts that the court recognized as being established, the legal principles the court is bound by, and the application of the relevant principles to the recognized facts. The goal is to demonstrate the rationale the court used in reaching its decision. [6]
As the second step of the European Union's infringement procedure, the European Commission issues a "reasoned opinion" when it is concerned that a Member State has not implemented a Directive or other EU law. The reasoned opinion, provided for under Article 258 of the Treaty on the Functioning of the European Union, [7] constitutes a formal request to the state concerned for implementing action to be taken, usually within a two month deadline. [8]
Also under EU law, a "reasoned opinion" may be issued by a Member State in relation to proposed EU legislation, if the Member State is concerned that the proposal infringes the EU's subsidiarity principle. Article 6, Protocol 2 to the Treaty of Lisbon (2007, entered into force on 1 December 2009) allows Member States to issue a reasoned opinion within 8 weeks of their official notification of the draft legislation. [9] As from 2019-20 the European Commission has allowed a longer period for reasoned opinions to be issued over the Christmas and New Year period. [10]
An expert report is a study written by one or more authorities that states findings and offers opinions.
In law, expert reports are generated by expert witnesses offering their opinions on points of controversy in a legal case and are typically sponsored by one side or the other in a litigation in order to support that party's claims. The reports state facts, discuss details, explain reasoning, and justify the experts' conclusions and opinions. [11]
In medicine, an expert report is a critical assessment of a medical topic, for example, an independent assessment of the cost–benefit ratio of a particular medical treatment. [12]
As part of survey pretesting, an expert report (using the expert review method) identifies potential problems that could affect data quality and data collection by evaluating survey questionnaires and survey translations. [13] [14] [15]An expert witness, particularly in common law countries such as the United Kingdom, Australia, and the United States, is a person whose opinion by virtue of education, training, certification, skills or experience, is accepted by the judge as an expert. The judge may consider the witness's specialized opinion about evidence or about facts before the court within the expert's area of expertise, to be referred to as an "expert opinion". Expert witnesses may also deliver "expert evidence" within the area of their expertise. Their testimony may be rebutted by testimony from other experts or by other evidence or facts.
Precedent is a principle or rule established in a legal case that becomes authoritative to a court or other tribunal when deciding subsequent cases with similar legal issues or facts. The legal doctrine stating that courts should follow precedent is called stare decisis.
The judiciary is the system of courts that adjudicates legal disputes/disagreements and interprets, defends, and applies the law in legal cases.
The European Court of Justice (ECJ), formally just the Court of Justice, is the supreme court of the European Union in matters of European Union law. As a part of the Court of Justice of the European Union, it is tasked with interpreting EU law and ensuring its uniform application across all EU member states under Article 263 of the Treaty of the Functioning of the European Union (TFEU).
A directive is a legal act of the European Union that requires member states to achieve particular goals without dictating how the member states achieve those goals. A directive's goals have to be made the goals of one or more new or changed national laws by the member states before this legislation applies to individuals residing in the member states. Directives normally leave member states with a certain amount of leeway as to the exact rules to be adopted. Directives can be adopted by means of a variety of legislative procedures depending on their subject matter.
Subsidiarity is a principle of social organization that holds that social and political issues should be dealt with at the most immediate or local level that is consistent with their resolution. The Oxford English Dictionary defines subsidiarity as "the principle that a central authority should have a subsidiary function, performing only those tasks which cannot be performed at a more local level". The concept is applicable in the fields of government, political science, neuropsychology, cybernetics, management and in military command. The OED adds that the term "subsidiarity" in English follows the early German usage of "Subsidiarität". More distantly, it is derived from the Latin verb subsidio, and the related noun subsidium.
Together, legal psychology and forensic psychology form the field more generally recognized as "psychology and law". Following earlier efforts by psychologists to address legal issues, psychology and law became a field of study in the 1960s as part of an effort to enhance justice, though that originating concern has lessened over time. The multidisciplinary American Psychological Association's Division 41, the American Psychology–Law Society, is active with the goal of promoting the contributions of psychology to the understanding of law and legal systems through research, as well as providing education to psychologists in legal issues and providing education to legal personnel on psychological issues. Further, its mandate is to inform the psychological and legal communities and the public at large of current research, educational, and service in the area of psychology and law. There are similar societies in Britain and Europe.
In United States federal law, the Daubert standard is a rule of evidence regarding the admissibility of expert witness testimony. A party may raise a Daubert motion, a special motion in limine raised before or during trial, to exclude the presentation of unqualified evidence to the jury. The Daubert trilogy are the three United States Supreme Court cases that articulated the Daubert standard:
Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993), is a United States Supreme Court case determining the standard for admitting expert testimony in federal courts. In Daubert, the Court held that the enactment of the Federal Rules of Evidence implicitly overturned the Frye standard; the standard that the Court articulated is referred to as the Daubert standard.
Attorney's fee is a chiefly United States term for compensation for legal services performed by an attorney for a client, in or out of court.
French law has a dual jurisdictional system comprising private law, also known as judicial law, and public law.
In common law jurisdictions, the generic term officer of the court is applied to all those who, in some degree in the function of their professional or similar qualifications, have a part in the legal system. Officers of the court may include entities such as judges, lawyers, and paralegals, and should not be confused with court officers, the law enforcement personnel who work in courts. In French-speaking jurisdictions, officers of the court, excluding judges, are known as auxiliaires de justice, not to be confused with judicial assistants.
The Court of Cassation of Belgium is the supreme court of the Belgian judiciary. The court is composed of thirty judges with life tenure who are nominated by the High Council of Justice of Belgium and appointed by the Belgian federal government. The court handles cases in the two main languages of Belgium, Dutch and French, and provides certain facilities for cases in German. The court is assisted in its work by a public prosecutor's office and a bar association, which both function separately from other structures. The duty of the public prosecutor's office is to provide advisory opinions to the court on how the law ought to be interpreted and applied. The attorneys of the court's bar association assist litigants in proceedings before the court; in certain cases, their assistance is mandatory.
In law, a legal opinion is in certain jurisdictions a written explanation by a judge or group of judges that accompanies an order or ruling in a case, laying out the rationale and legal principles for the ruling.
The legal process school was a movement within American law that attempted to chart a third way between legal formalism and legal realism. Drawing its name from Hart & Sacks' textbook The Legal Process, it is associated with scholars such as Herbert Wechsler, Henry Hart, Albert Sacks and Lon Fuller, and their students such as John Hart Ely and Alexander Bickel. The school grew in the 1950s and 1960s. To this day, the school's influence remains broad.
Legal financing is the mechanism or process through which litigants can finance their litigation or other legal costs through a third party funding company.
An expert report is a study written by one or more authorities that states findings and offers opinions.
Legal Services Corp. v. Velazquez, 531 U.S. 533 (2001), is a decision of the Supreme Court of the United States concerning the constitutionality of funding restrictions imposed by the United States Congress. At issue were restrictions on the Legal Services Corporation (LSC), a private, nonprofit corporation established by Congress. The restrictions prohibited LSC attorneys from representing clients attempting to amend existing welfare law. The case was brought by Carmen Velazquez, whose LSC-funded attorneys sought to challenge existing welfare provisions since they believed that it was the only way to get Velazquez financial relief.
The general principles of European Union law are general principles of law which are applied by the European Court of Justice and the national courts of the member states when determining the lawfulness of legislative and administrative measures within the European Union. General principles of European Union law may be derived from common legal principles in the various EU member states, or general principles found in international law or European Union law. General principles of law should be distinguished from rules of law as principles are more general and open-ended in the sense that they need to be honed to be applied to specific cases with correct results.
Opinion 2/13 (2014) is an EU law case determined by the European Court of Justice, concerning the accession of the European Union to the European Convention on Human Rights, and more generally the relationship between the European Court of Justice and European Court of Human Rights.
