(5 ILCS 70/6)
(from Ch. 1, par. 1105)
Two or more Acts which relate to same subject matter and which are
enacted by the same General Assembly shall be construed together in such
manner as to give full effect to each Act except in case of an
irreconcilable conflict. In case of an irreconcilable conflict the Act
last acted upon by the General Assembly is controlling to the extent of
such conflict. The Act last acted upon is determined by reference to the
final legislative action taken by either house of the General Assembly,
whether such final action is passage on third reading in the second
house, concurring in or receding from an amendment, adoption of a
conference committee report, acceptance of the Governor's specific
recommendations for change, or passage over the Governor's veto.
However, for the purpose of determining the effective date of laws under
Section 10 of Article IV of the Constitution of 1970 and "An Act in
relation to the effective date of laws", approved July 2, 1971, a bill
is "passed" at the time of its final legislative action before
presentation to the Governor as provided in paragraph (a) of Section 9
of Article IV of the Constitution of 1970.
An irreconcilable conflict between 2 or more Acts which amend the
same section of an Act exists only if the amendatory Acts make
inconsistent changes in the section as it theretofore existed.
The rules of construction provided for in this section are applicable
to Acts enacted by the same General Assembly throughout the 2 year
period of its existence.
