A BILL TO BE ENTITLED
 
AN ACT
  relating to the standard of causation in claims involving
  mesothelioma caused by exposure to asbestos fibers.
         BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF TEXAS:
         SECTION 1.  Chapter 90, Civil Practice and Remedies Code, is
  amended by adding Section 90.013 to read as follows:
         Sec. 90.013.  STANDARD OF CAUSATION FOR CLAIMS INVOLVING
  MALIGNANT MESOTHELIOMA.  (a)  To recover damages for malignant
  mesothelioma allegedly caused by exposure to asbestos or asbestos
  containing products, the claimant must prove, among other elements
  of the claim, that a defendant's product or conduct was a
  substantial factor in causing the claimant's injury.
         (b)  A defendant's product or conduct was a substantial
  factor in causing the exposed claimant's injury if the claimant
  presents qualitative proof that the asbestos exposure attributed to
  the defendant was substantial, and not merely de minimis, when
  considering:
               (1)  the frequency of the exposure;
               (2)  the regularity of the exposure; and
               (3)  the proximity of the claimant to the source of the
  asbestos fibers.
         (c)  A defendant who seeks a determination of the percentage
  of responsibility of another person under Section 33.003(a) must
  present qualitative proof in the same manner as is required of a
  claimant under Subsection (b).
         (d)  A claimant or a defendant, including a defendant seeking
  a determination under Section 33.003(a), shall not be required to
  prove, or be prohibited from proving through otherwise admissible
  evidence, the numerical dose, approximate or otherwise, of asbestos
  fibers to which the claimant was exposed that are attributable to
  the defendant or another person under Section 33.003(a).
         (e)  Nothing in this section modifies the general legal
  requirements for the admissibility of expert testimony with respect
  to the issue of causation.
         SECTION 2.  Section 90.013, Civil Practice and Remedies
  Code, as added by this Act, applies to an action commenced on or
  after the effective date of this Act or pending on the effective
  date of this Act and in which the trial, or any new trial or retrial
  following motion, appeal, or otherwise, has not commenced on or
  before the effective date of this Act. An action commenced before
  the effective date of this Act in which trial has commenced on or
  before the effective date of this Act or in which there has been a
  final, unappealable disposition by order, judgment, voluntary
  dismissal, or otherwise is governed by the law applicable to the
  action immediately before the effective date of this Act, and that
  law is continued in effect for that purpose.
         SECTION 3.  If any 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 this Act that can be
  given effect without the invalid provision or application, and to
  this end the provisions of this Act are declared to be severable.
         SECTION 4.  This Act takes effect immediately if it receives
  a vote of two-thirds of all the members elected to each house, as
  provided by Section 39, Article III, Texas Constitution.  If this
  Act does not receive the vote necessary for immediate effect, this
  Act takes effect September 1, 2009.
