SECTION 2. LEGISLATIVE COMPOSITION
    (a)  One Senator shall be elected from each Legislative
District. Immediately following each decennial redistricting,
the General Assembly by law shall divide the Legislative
Districts as equally as possible into three groups. Senators
from one group shall be elected for terms of four years, four
years and two years; Senators from the second group, for
terms of four years, two years and four years; and Senators
from the third group, for terms of two years, four years and
four years. The Legislative Districts in each group shall be
distributed substantially equally over the State.
    (b)  Each Legislative District shall be divided into two
Representative Districts. In 1982 and every two years
thereafter one Representative shall be elected from each
Representative District for a term of two years.
    (c)  To be eligible to serve as a member of the General
Assembly, a person must be a United States citizen, at least
21 years old, and for the two years preceding his election or
appointment a resident of the district which he is to
represent. In the general election following a redistricting,
a candidate for the General Assembly may be elected from any
district which contains a part of the district in which he
resided at the time of the redistricting and reelected if a
resident of the new district he represents for 18 months
prior to reelection.
    (d)  Within thirty days after a vacancy occurs, it shall
be filled by appointment as provided by law. If the vacancy
is in a Senatorial office with more than twenty-eight months
remaining in the term, the appointed Senator shall serve
until the next general election, at which time a Senator
shall be elected to serve for the remainder of the term. If
the vacancy is in a Representative office or in any other
Senatorial office, the appointment shall be for the remainder
of the term. An appointee to fill a vacancy shall be a member
of the same political party as the person he succeeds.
    (e)  No member of the General Assembly shall receive
compensation as a public officer or employee from any other
governmental entity for time during which he is in attendance
as a member of the General Assembly.
    No member of the General Assembly during the term for
which he was elected or appointed shall be appointed to a
public office which shall have been created or the
compensation for which shall have been increased by the
General Assembly during that term.

    (a)  Legislative Districts shall be compact, contiguous
and substantially equal in population. Representative
Districts shall be compact, contiguous, and substantially
equal in population.
    (b)  In the year following each Federal decennial census
year, the General Assembly by law shall redistrict the
Legislative Districts and the Representative Districts.

constituted not later than July 10. The Commission shall
consist of eight members, no more than four of whom shall be
members of the same political party.
    The Speaker and Minority Leader of the House of
Representatives shall each appoint to the Commission one
Representative and one person who is not a member of the
General Assembly. The President and Minority Leader of the
Senate shall each appoint to the Commission one Senator and

by the appointing authorities. A vacancy on the Commission
shall be filled within five days by the authority that made
the original appointment. A Chairman and Vice Chairman shall
be chosen by a majority of all members of the Commission.

the Secretary of State a redistricting plan approved by at
least five members.
    If the Commission fails to file an approved redistricting
plan, the Supreme Court shall submit the names of two
persons, not of the same political party, to the Secretary of
State not later than September 1.
    Not later than September 5, the Secretary of State
publicly shall draw by random selection the name of one of
the two persons to serve as the ninth member of the
Commission.
    Not later than October 5, the Commission shall file with
the Secretary of State a redistricting plan approved by at

of State shall be presumed valid, shall have the force and
effect of law and shall be published promptly by the
Secretary of State.
    The Supreme Court shall have original and exclusive
jurisdiction over actions concerning redistricting the House

Bills may originate in either house, but may be amended or

SECTION 9. VETO PROCEDURE
    (a)  Every bill passed by the General Assembly shall be
presented to the Governor within 30 calendar days after its
passage. The foregoing requirement shall be judicially
enforceable. If the Governor approves the bill, he shall sign
it and it shall become law.
    (b)  If the Governor does not approve the bill, he shall
veto it by returning it with his objections to the house in
which it originated. Any bill not so returned by the Governor
within 60 calendar days after it is presented to him shall
become law. If recess or adjournment of the General Assembly
prevents the return of a bill, the bill and the Governor's
objections shall be filed with the Secretary of State within
such 60 calendar days. The Secretary of State shall return
the bill and objections to the originating house promptly
upon the next meeting of the same General Assembly at which
the bill can be considered.
    (c)  The house to which a bill is returned shall
immediately enter the Governor's objections upon its journal.
If within 15 calendar days after such entry that house by a
record vote of three-fifths of the members elected passes the
bill, it shall be delivered immediately to the second house.
If within 15 calendar days after such delivery the second
house by a record vote of three-fifths of the members elected
passes the bill, it shall become law.
    (d)  The Governor may reduce or veto any item of
appropriations in a bill presented to him. Portions of a bill
not reduced or vetoed shall become law. An item vetoed shall
be returned to the house in which it originated and may
become law in the same manner as a vetoed bill. An item
reduced in amount shall be returned to the house in which it
originated and may be restored to its original amount in the
same manner as a vetoed bill except that the required record
vote shall be a majority of the members elected to each
house. If a reduced item is not so restored, it shall become
law in the reduced amount.
    (e)  The Governor may return a bill together with
specific recommendations for change to the house in which it
originated. The bill shall be considered in the same manner
as a vetoed bill but the specific recommendations may be
accepted by a record vote of a majority of the members
elected to each house. Such bill shall be presented again to
the Governor and if he certifies that such acceptance
conforms to his specific recommendations, the bill shall
become law. If he does not so certify, he shall return it as
a vetoed bill to the house in which it originated.

effective date for laws passed prior to June 1 of a calendar
year. The General Assembly may provide for a different
effective date in any law passed prior to June 1. A bill
passed after May 31 shall not become effective prior to June
1 of the next calendar year unless the General Assembly by
the vote of three-fifths of the members elected to each house
provides for an earlier effective date.

SECTION 14. IMPEACHMENT
    The House of Representatives has the sole power to
conduct legislative investigations to determine the existence
of cause for impeachment and, by the vote of a majority of
the members elected, to impeach Executive and Judicial
officers. Impeachments shall be tried by the Senate. When
sitting for that purpose, Senators shall be upon oath, or
affirmation, to do justice according to law. If the Governor
is tried, the Chief Justice of the Supreme Court shall
preside. No person shall be convicted without the concurrence
of two-thirds of the Senators elected. Judgment shall not
extend beyond removal from office and disqualification to
hold any public office of this State. An impeached officer,
whether convicted or acquitted, shall be liable to
prosecution, trial, judgment and punishment according to law.
