ARTICLE ___.  APPEAL OF ORDER OF APPRAISAL REVIEW BOARD
	SECTION ___.01.  Section 42.23, Tax Code, is amended by 
adding Subsections (d) and (e) to read as follows:
	(d)  Each party to an appeal is considered a party seeking 
affirmative relief for the purpose of discovery regarding expert 
witnesses under the Texas Rules of Civil Procedure if, on or before 
the 120th day after the date the appeal is filed, the property 
owner:
		(1)  makes a written offer of settlement;                              
		(2)  requests alternative dispute resolution; and                      
		(3)  designates, in response to an appropriate written 
discovery request, which cause of action under this chapter is the 
basis for the appeal.
	(e)  For purposes of Subsection (d), a property owner may 
designate a cause of action under Section 42.25 or 42.26 as the 
basis for an appeal, but may not designate a cause of action under 
both sections as the basis for the appeal.  Discovery regarding a 
cause of action that is not specifically designated by the property 
owner under Subsection (d) shall be conducted as provided by the 
Texas Rules of Civil Procedure.
	SECTION ___.02.  The change in law made by this article 
applies only to an appeal of an appraisal review board order if the 
appeal is filed or amended on or after the effective date of this 
Act.  An appeal filed or amended before the effective date of this 
Act is covered by the law in effect when the appeal was filed or 
amended, and the former law is continued in effect for that purpose.
