Most people believe that majority rule is a fair way for laws to be passed and to be exercised in their country, and on the surface, this seems to be fair, as what the majority so desires, in a fair election, or through the fair evaluation by its legislature, should rightly be the law. However, as sound as that may well seem on the surface, there is fundamentally a problem with majority rule, when that majority, is permitted to pass laws that benefits that majority at the expense of the minority in which, therefore, that country thereupon devolves into essentially becoming a country of "mob rule".
So that, the qualification for majority rule should be based around a well written Constitution that serves to represent well the governing instrument of that country, of which that Constitution contains within it checks and balances, that guarantee first and foremost to each one of those citizens their unalienable rights, which thereby belongs to those citizens by birth and not by the pen of that government, but rather by the very hand of God, which therefore makes them unalienable. Further to the point, the highest law of any land should always be that law which is immutable, true, and moral in its construction, and thereupon equal in its application, and thereby no respecter of persons, but only that which is the respecter of that law which is fair and just, which is natural law.
Natural law is that which is for the common good of all mankind, for the propagation of that which is of benefit for mankind, and of which, fair reason, recognizes such as being an unchangeable and fixed moral law, applicable to all. That is to say, the very purpose of any good law is that the construction and thereby the application of such is universal, fair, and just, of which, the purpose of such a law, is for the wholesale benefit of those people that are under that law.
So then, within any majority rule of any country, there has to be applied to such, ethical universal laws, which supersede mankind's laws, and further that the Constitution of that country, must in its construction and usage, sustain in such a manner as to at all times, protect and defend the weakest and the disenfranchised that are part of parcel of all societies, so as to continually recognize that each person, by virtue of their birth, has unalienable rights, of which it is the responsibility of that governance to see that none of these unalienable rights are ever trampled upon by arbitrary majority rule.
Again, that which the majority wants and so wills, is theirs to have, contingent upon those laws so being passed, being in accordance with the Constitution of that country, and in harmony with natural law. For, in absence of these very things, majority rule, devolves into a tyranny of those that have the exclusive power and thereupon uses such over all those of the minority that have no sanctuary to preclude that power from running roughshod over them. So that, the checks and balances of a robust Constitution, in conjunction with natural law, thereby permits that which the majority so desires, within those necessary constraints.
