e prescribed by
congress. In pursuance of the power here granted, congress has enacted,
that a certificate under seal of the clerk of a court of record,
transmitted to any state of the union, shall there be deemed evidence
of the facts therein stated. But if the thing certified is a judicial
proceeding, such sealed certificate must be accompanied by the
certificate of the presiding judge or justice, that the attestation of
the clerk is in due form. Acts of a state legislature, to be entitled to
credit in another state, must have the seal of the state affixed to
them.

Sec.3. The next section of this article provides, that "the citizens of
each state shall be entitled to all the immunities and privileges of
citizens in the several states." This means that the citizens of any
state going into other states, shall not, by the laws of those states,
be deprived of any of the privileges of citizens; but shall be entitled
to the privileges which are enjoyed by persons of the same description
in the states to which they remove. Without such a provision, any state
might deny to citizens coming into it from other states, the right to
buy and hold real estate, or to become voters, or to enjoy equal
privileges in trade or business. A state may, however, prescribe a
certain term of residence therein as a qualification for voting at
elections.

Sec.4. The next clause of this section provides for apprehending "a person
charged with crime, who shall flee from justice and be found in another
state." The governor of the state from which such person has fled, sends
a requisition to the governor of the state in which he is found,
demanding his delivery to the proper officers, to be conveyed back for
trial. Without such authority to apprehend criminals, they might escape
justice by taking shelter in another state.

Sec.5. In the same section it is provided, that "no person held to service
or labor in one state, under the laws thereof, escaping into another,
shall, in consequence of any law or regulation therein, be discharged
from such service or labor, but shall be delivered up on claim of the
party to whom such service or labor may be due." This clause was
intended for the benefit of the slaveholding states. By the common law,
a slave escaping into a non-slaveholding state became free. As it was
presumed that other northern states would follow Massachusetts in
abolishing slavery, the southern states wanted some provision to enable
them
