Sec. 3. Evidence of prior criminal record in all criminal cases after a finding of guilty.
(a)(1) Regardless of the plea and whether the punishment be assessed by the judge or the jury, evidence may be offered by the state and the defendant as to any matter the court deems relevant to sentencing, including but not limited to the prior criminal record of the defendant, his general reputation, his character, an opinion regarding his character, the circumstances of the offense for which he is being tried, and, notwithstanding Rules 404 and 405, Texas Rules of Evidence, any other evidence of an extraneous crime or bad act that is shown beyond a reasonable doubt by evidence to have been committed by the defendant or for which he could be held criminally responsible, regardless of whether he has previously been charged with or finally convicted of the crime or act.  A court may consider as a factor in mitigating punishment the conduct of a defendant while participating in a program under Chapter 17 as a condition of release on bail.  Additionally, notwithstanding Rule 609(d), Texas Rules of Evidence, and subject to Subsection (h), evidence may be offered by the state and the defendant of an adjudication of delinquency based on a violation by the defendant of a penal law of the grade of:
(A) a felony;  or
(B) a misdemeanor punishable by confinement in jail.
(2) Notwithstanding Subdivision (1), evidence may not be offered by the state to establish that the race or ethnicity of the defendant makes it likely that the defendant will engage in future criminal conduct.
(3)  Regardless of the plea and whether the punishment is assessed by the judge or the jury, during the punishment phase of the trial of an offense under Section 35A.02, Penal Code, subject to the applicable rules of evidence, the state and the defendant may offer evidence not offered during the guilt or innocence phase of the trial concerning the total pecuniary loss to the affected health care program caused by the defendant's conduct or, if applicable, the scheme or continuing course of conduct of which the defendant's conduct is part.  Evidence may be offered in summary form concerning the total pecuniary loss to the affected health care program.  Testimony regarding the total pecuniary loss to the affected health care program is subject to cross-examination.  Evidence offered under this subdivision may be considered by the judge or jury in ordering or recommending the amount of any restitution to be made to the affected health care program or the appropriate punishment for the defendant.
(b) After the introduction of such evidence has been concluded, and if the jury has the responsibility of assessing the punishment, the court shall give such additional written instructions as may be necessary and the order of procedure and the rules governing the conduct of the trial shall be the same as are applicable on the issue of guilt or innocence.
(c)  If the jury finds the defendant guilty and the matter of punishment is referred to the jury, the verdict shall not be complete until a jury verdict has been rendered on both the guilt or innocence of the defendant and the amount of punishment.  In the event the jury shall fail to agree on the issue of punishment, a mistrial shall be declared only in the punishment phase of the trial, the jury shall be discharged, and no jeopardy shall attach.  The court shall impanel another jury as soon as practicable to determine the issue of punishment.
(d)  When the judge assesses the punishment, the judge may order a presentence report as contemplated in Subchapter F, Chapter 42A, and after considering the report, and after the hearing of the evidence hereinabove provided for, the judge shall forthwith announce the judge's decision in open court as to the punishment to be assessed.
(e) Nothing herein contained shall be construed as affecting the admissibility of extraneous offenses on the question of guilt or innocence.
(f) In cases in which the matter of punishment is referred to a jury, either party may offer into evidence the availability of community corrections facilities serving the jurisdiction in which the offense was committed.
(g)  On timely request of the defendant, notice of intent to introduce evidence under this article shall be given in the same manner required by Rule 404(b), Texas Rules of Evidence.  If the attorney representing the state intends to introduce an extraneous crime or bad act that has not resulted in a final conviction in a court of record or a probated or suspended sentence, notice of that intent is reasonable only if the notice includes the date on which and the county in which the alleged crime or bad act occurred and the name of the alleged victim of the crime or bad act.  The requirement under this subsection that the attorney representing the state give notice applies only if the defendant makes a timely request to the attorney representing the state for the notice.
(h) Regardless of whether the punishment will be assessed by the judge or the jury, neither the state nor the defendant may offer before sentencing evidence that the defendant plans to undergo an orchiectomy.
(i) Evidence of an adjudication for conduct that is a violation of a penal law of the grade of misdemeanor punishable by confinement in jail is admissible only if the conduct upon which the adjudication is based occurred on or after January 1, 1996.
