FACT SHEET FOR
S.B. 1573

judicial
determinations; religious sectarian laws

Purpose

Prohibits a court from relying on religious sectarian law as controlling
or persuasive authority.

Background

Foreign law
is any law, rule, legal code or legal system other
than the U.S. Constitution, laws and ratified treaties of the United States and
U.S. territories or the Arizona Constitution and state law. A court,
arbitrator, administrative agency or other adjudicative, mediation or
enforcement authority may not enforce a foreign law if doing so would violate a
right guaranteed by the U.S. or Arizona Constitution or conflict with state or
federal law. The foreign law definition and prohibition apply only when the
application of foreign law results in a violation of a person's constitutional
rights or a conflict with state law and does not apply to corporations,
partnerships or other forms of business association (A.R.S. ��
12-3101

and
12-3102
).

There is no anticipated fiscal impact to the state General Fund
associated with this legislation.

a court from relying on religious sectarian law as controlling or persuasive authority.

that is based on Anglo-American legal tradition and principles on which the

Britain before the general effective date; and

c)

the recognition of a traditional marriage between a man and a woman as
officiated by the clergy or secular official of the matrimonial couple's
choice.

4.

Defines
religious sectarian law
as any statute, tenet or body of
law evolving within and binding a specific religious sect or tribe
and does
not include any law of the United States or the individual states based on
Anglo-American legal tradition and principles.

5.

Requires
a court, when construing requirements and limitations related to religious
sectarian law, to adopt a construction that:

a)

confines the powers of the U.S. Congress and the federal judiciary to
impose religious sectarian law to the least expansive interpretation permitted
under binding precedent;

b)

secures the state's authority to regulate its courts under the Tenth
Amendment of the U.S. Constitution to the greatest extent permitted under

c)

the constitutional rights of Arizonans under Article 1, Section 8 of the U.S.
Constitution, as well as the First, Ninth and Tenth Amendments to the U.S.
Constitution to regulate Arizona's judiciary permitted under binding precedent.

Legislative findings

The legislature finds that:

1. The tenth amendment to
the United States Constitution guarantees and reserves to the states or their
people all powers not specifically granted to the federal government elsewhere
in the constitution as they were publicly understood at the time the amendment
was ratified on December 15, 1791, subject only to modification by duly
ratified subsequent amendments to the United States Constitution. The
guaranty of those powers is a matter of compact between the state and people of
Arizona and the United States as of the time Arizona was admitted to statehood
on February 14, 1912.

2. As a matter of compact
between the state and people of Arizona and the United States as of the time
Arizona was admitted to statehood on February 14, 1912, the tenth amendment to
the United States Constitution guarantees to the state and people of Arizona
that other than the enumerated powers expressly granted to the United States
under article I, section 8 of the United States Constitution, Congress and the
federal government will not exercise any purported control over or commandeer
the courts of the state of Arizona.

3. At the time the United
States Constitution was ratified on June 21, 1788, the sole and sovereign power
to regulate the state courts rested in the state legislature and has always
been a compelling state concern and central to state sovereignty. Accordingly,
the foregoing public meaning and understanding of article I, section 8, the
establishment clause of the first amendment and the tenth amendment of the
United States Constitution are matters of compact between the state and people
of Arizona and the United States as of the time Arizona was admitted to
statehood on February 14, 1912.

4. At the time the United
States Constitution was ratified on June 21, 1788, the commerce clause was not
meant or understood to authorize Congress or the federal judiciary to regulate
the state courts in the matter of state substantive law or state judicial
procedure. The meaning and understanding of article I, section 8,
the establishment clause of the first amendment and the tenth amendment of the
United States Constitution, as they pertain to the validity of religious
sectarian law as being controlling or influential precedent, have never been
modified by any duly ratified amendment to the United States Constitution. Accordingly,
the foregoing public meaning and understanding of article I, section 8 and the
tenth amendment of the United States Constitution are matters of compact
between the state and people of Arizona and the United States as of the time
Arizona was admitted to statehood on February 14, 1912.

5. At the time the United
States Constitution was ratified on June 21, 1788, the commerce clause was not
meant or understood to authorize Congress or the federal judiciary to establish
religious sectarian statute or case law as controlling or influential
precedent. The meaning and understanding of article I, section 8,
the establishment clause of the first amendment and the tenth amendment of the
United States Constitution, as they pertain to controlling or influential legal
authority, have never been modified by any duly ratified amendment to the
United States Constitution. Accordingly, the foregoing public
meaning and understanding of article I, section 8, the establishment clause of
the first amendment and the tenth amendment of the United States Constitution
are matters of compact between the state and people of Arizona and the United
States as of the time Arizona was admitted to statehood on February 14, 1912.

6. The Congress and the
federal government are denied the power to establish a sectarian religion by
recognizing or ratifying judicial decisions based on religious sectarian law.

7.
Under
the tenth amendment of the United States Constitution, the people and state of
Arizona retain their exclusive power to regulate the state courts of Arizona
subject only to the fourteenth amendment's guarantee that the people and state
of Arizona shall exercise such sovereign power in accordance with each
citizen's lawful privileges or immunities, and in compliance with the
requirements of due process and equal protection of the law.

8.
The
ninth amendment of the United States Constitution secures and reserves to the
people of Arizona as against the federal government their natural rights to
life, liberty and property as entailed by the traditional Anglo-American
conception of ordered liberty and as secured by state law, including their
rights as they were understood and secured by the law at the time the amendment
was ratified on December 15, 1791, as well as their rights as they were
understood and secured by the law in the state of Arizona at the time the
Arizona Constitution was adopted on December 9, 1910. The guarantee
of those rights is a matter of compact between the state and people of Arizona
and the United States as of the time Arizona was admitted to statehood on
February 14, 1912.

Sec.
6.
6.
Construction and severability

A. Any court that construes
this act must adopt a construction of each provision that:

1. Confines the power of
Congress and the federal judiciary to impose religious sectarian law to the
least expansive interpretation permitted under binding precedent.

2. Secures the authority of
the state of Arizona to exclusively regulate its courts under the tenth
amendment of the United States Constitution to the greatest extent permitted
under binding precedent.

3. Protects
the constitutional rights of Arizonans under article I, section 8 of the United
States Constitution, as well as the first, ninth and tenth amendments to the
United States Constitution to regulate the state's judiciary permitted under
binding precedent.

B. If a provision of this
act or its application to any person or circumstance is held invalid, the
invalidity does not affect other provisions or applications of the act that can
be given effect without the invalid provision or application, and to this end
the provisions of this act are severable.
