The statement ties the binding force of a law strictly to the political sovereignty of its maker, not to its moral worth or social utility. Assessing each school of jurisprudential thought against this idea helps identify which one fits.
Only the positivist account roots the validity of a rule exclusively in the political authority of its source, which is precisely what the statement describes.
Hence, the correct answer is Legal Positivism.
The statement says a norm needs fair and just content before it can be legally valid, which is a claim about the relationship between morality and legal validity. Each school is checked against this claim.
Because the statement makes moral content a precondition of validity, it belongs to Natural Law.
Hence, the correct answer is Natural Law.
The quotation criticises legal positivism for reducing law to rules alone and draws a logical distinction between rules and principles, which points to a specific critique made by a named jurist against positivism.
The rules-versus-principles critique of positivism, phrased as a "falsehood", is Dworkin's signature argument from Taking Rights Seriously.
Hence, the correct answer is Ronald Dworkin, Taking Rights Seriously, 1977.
The list of qualities given, generality, publicity, prospectivity, coherence, clarity, stability and practicability, is a fixed set of procedural requirements associated with a specific jurisprudential formulation.
The precise seven-item list corresponds to Fuller's inner morality of law, not to any of the other labels.
Hence, the correct answer is Inner Morality.
The quotation links the study of legal history to understanding the present and shaping the future, a reflective observation on the function of history in law that is associated with a particular jurist's writing on judicial method.
The reflective tone linking past, present and future through history fits the judicial-method writing associated with Cardozo among the given options.
Hence, the correct answer is Benjamin Cardozo.
This is one of the most quoted opening lines in American legal writing, and identifying its author rests on recognising both the phrase and the work it opens.
The sentence is the opening line of Holmes's The Common Law and is firmly attributed to him.
Hence, the correct answer is Holmes.
