How can I view congressional redistricting bills from previous legislative sessions?
The Legislative Reference Library has compiled a list of all redistricting bills introduced in the Texas Legislature from the 17th Legislature (1881) through the 81st Legislature (2009).  Go to Congressional Redistricting Bills in Texas, 17th-81st Legislatures.

Is congressional redistricting required by the constitution?
Yes.  The United States constitution calls for reapportionment of congressional seats according to the population from a decennial census (Section 2, Article I).  The Texas Constitution requires the legislature to redistrict Texas house and senate seats during its first regular session following publication of each United States decennial census (Section 28, Article III).  For additional information on legal requirements, see Texas Redistricting - Legal Requirements for the Process.
