There is no universal consensus on how to define the term "cult". There are multiple competing definitions.
In 1932, the sociologist Howard P. Becker introduced a fourfold classification of religious groups, into cults, sects, denominations and ecclesias (which was in turn an expansion of the theologian Ernst Troeltsch's earlier two-fold classification of religious groups as "churches" or "sects"). Cults and sects are religious groups with a high degree of tension with the surrounding society; cults have novel beliefs (in the context of that society), sects have traditional beliefs. Denominations are established religious groups with low tension with their society, but who do not dominate it. An ecclesia is a de jure or de facto state religion. By this set of definitions, cults are religions, if by "religion" one means "religious group". Many sociologists of religion continue to use Becker's definitions today; they are still part of the standard content of most university-level introductory courses on the sociology of religion – although not all sociologists endorse them, and some have put forward alternative proposals (such as Roy Wallis' proposal that the defining feature of cults is "epistemological individualism".)
In most sociological use, "cult" is a value-neutral, non-judgemental term; in colloquial English, it has become a derogatory term, implying the group is harmful or aberrant. Some psychologists have developed formal definitions of "cults" as psychologically harmful organisations – it appears those psychologists were ignorant of the prior use of the term in sociology (or, possibly, knew about it but didn't care.) Many evangelical Christians promote a theological definition of the term "cult", in which it essentially means "Christian group we judge to be heretical"–in some cases, the label "cult" is even extended to include all non-Christian religions.
You seem to be suggesting there is some legal definition of the term "cult", in the case law of some American states, including a legal distinction between "cult" and "religion". As evidence for this, you point to a newspaper article summarising the 1988 Supreme Court of California decision Molko v. Holy Spirit Assn. However, the newspaper article you cite never actually uses the word "cult" non-attributively–it is citing the use of the word by others, not using the word itself–and it is citing the use of the word by the plaintiff's expert witnesses and by activist groups, not the Court's justices as using the word.
And, if you read the actual text of the decision [0], while it cites a number of journal articles and books with the word Cult in their titles, it never actually uses that word itself. I am wondering if maybe you are projecting this binary distinction which exists in your own mind, between "cults" and "religions", on to case law in which that distinction is never actually drawn. On the contrary, Justice Stanley Mosk's decision assumes that the alleged "cult" (in this case, The Unification Church) is a religion, and the case turns on what are the legal standards for fraud and emotional distress claims against religious groups. The Court's judgement is that you can sue a religious group for fraud and emotional distress, by alleging deceptive recruiting practices, brainwashing, etc; and that such lawsuits are not barred by the First Amendment. The actual decision doesn't turn at all on any cult-vs-religion distinction, the same legal standard applies to all religious groups, whether "cults" or not. And it was not a decision on whether or not the Unification Church actually had engaged in any such activities, or whether they were a "cult"; it was simply a preliminary ruling that the case against them could proceed to trial. (Ultimately, the case never went to trial, it was settled.)
