In determining that the School Committee have no _power_ to make this discrimination we are strengthened by another consideration. If the power exists in the present case, it cannot be restricted to this. The Committee may distribute all the children into classes, according to mere discretion. They may establish a separate school for Irish or Germans, where each may nurse an exclusive nationality alien to our institutions. They may separate Catholics from Protestants, or, pursuing their discretion still further, may separate different sects of Protestants, and establish one school for Unitarians, another for Presbyterians, another for Baptists, and another for Methodists. They may establish a separate school for the rich, that the delicate taste of this favored class may not be offended by the humble garments of the poor. They may exclude the children of mechanics, and send them to separate schools. All this, and much more, can be done in the exercise of that high-handed power which makes a discrimination on account of race or color. The grand fabric of our Common Schools, the pride of Massachusetts,--where, at the feet of the teacher, innocent childhood should come, unconscious of all distinctions of birth,--where the Equality of the Constitution and of Christianity should be inculcated by constant precept and example,--will be converted into a heathen system of proscription and Caste. We shall then have many different schools, representatives of as many different classes, opinions, and prejudices; but we shall look in vain for the true Common School of Massachusetts. Let it not be said that there is little danger that any Committee will exercise a discretion to this extent. They must not be intrusted with the power. Here is the only safety worthy of a free people. * * * * * BY-LAW VOID. The Court will declare the by-law of the School Committee unconstitutional and illegal, although there are no express words of prohibition in the Constitution and Laws. It is hardly necessary to say anything in support of this proposition. Slavery was abolished in Massachusetts, under the Declaration of Rights in our Constitution, without any specific words of abolition in that instrument, or in any subsequent legislation.[44] The same words which are potent to destroy Slavery must be equally potent against any institution founded on Inequality or Caste. The case of _Boston_ v. _Shaw_ (1 Metcalf, 130), to which reference has been already made, where a by-law of the city was set aside as unequal and unreasonable, and therefore void, affords another example of the power which I here invoke. But authorities are not needed. The words of the Constitution are plain, and it will be the duty of the Court to see that they are applied to the discrimination now waiting for judgment.
