to render a final judgment must be lodged somewhere; and there is no
provision in the Federal Constitution which forbids a State from
granting to a tribunal, whether called a court or an administrative
board, the final determination of a legal question. Neither in
administrative nor judicial proceedings does the due process clause
require that the participants be entitled as of right to rehearings, new
trials, or appeals.[994]

Federal Review of State Procedure

The Fourteenth Amendment does not impair the authority of the States to
determine finally, according to their settled usages and established
modes of procedure, issues which do not involve any right secured by the
Constitution, an act of Congress, or a treaty. As long as a local
tribunal acts in consonance with the Constitution, laws and procedure of
its own State and as long as said Constitution and laws are so
interpreted as not to violate due process, it is only in exceptional
circumstances that the Supreme Court would feel justified in
intervening. Neither by intention nor by result has the Fourteenth
Amendment transformed the Supreme Court into a court of general review
to which questions of general justice or equitable consideration arising
out of the taking of property may be brought for final
determination.[995]

Insofar as mere irregularities or errors in matters of practice under
State procedure do not affect constitutional right,[996] they are
matters solely for consideration by the appropriate State tribunal.[997]
The Constitution does not guarantee that the decisions of State courts
shall be free from error;[998] nor does the due process clause give the
Supreme Court jurisdiction to review mere mistakes of law concerning
nonfederal matters alleged to have been committed by a State court.[999]
Accordingly, when statutes authorizing the form of the indictment used
are not obviously violative of fundamental constitutional principles,
any question as to the sufficiency of the indictment employed is for a
State court to determine.[1000] Likewise, the failure of a State to
establish a county appellate court as required by the State constitution
cannot support any appeal founded upon a denial of due process.[1001]
Moreover, if a State court errs in deciding what the common law is,
without, however, denying any constitutional right, the litigant
adversely affected is not deprived of any liberty or property without
due process of law.[1002] Also, wh
