liberty, under any pretense whatever, may prosecute a writ of habeas
corpus, to inquire into the cause of such imprisonment or restraint.

(b) A writ of habeas corpus may be prosecuted for, but not limited
to, the following reasons:
(1) False evidence that is substantially material or probative on
the issue of guilt or punishment was introduced against a person at
any hearing or trial relating to his incarceration; or
(2) False physical evidence, believed by a person to be factual,
probative, or material on the issue of guilt, which was known by the
person at the time of entering a plea of guilty, which was a material
factor directly related to the plea of guilty by the person.
(c) Any allegation that the prosecution knew or should have known
of the false nature of the evidence referred to in subdivision (b) is
immaterial to the prosecution of a writ of habeas corpus brought
pursuant to subdivision (b).
(d) Nothing in this section shall be construed as limiting the
grounds for which a writ of habeas corpus may be prosecuted or as
precluding the use of any other remedies.
