Ex Parte Chamberlain, 335 S.W.3d 198

Chamberlain pled guilty in 1997 to sexual assault, a third-degree felony, with deferred adjudication and four years of community supervision.
He completed the supervision term in October 2001, but remains subject to lifetime sex-offender registration.
In 2008, Chamberlain filed a habeas corpus petition asserting lifetime registration violates substantive due process due to no mechanism for future risk reassessment.
The trial court denied relief; the Fort Worth Court of Appeals rejected the claim, relying on a statutory framework for possible early termination of registration.
The appellate court described Articles 62.401–62.408 and 62.403 as enabling individualized risk assessment and potential early termination.
After discretionary review was granted, the CSOT issued a list in December 2010 showing deregistration is not available for individuals convicted of sexual assault, altering the legal landscape.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Does lifetime registration violate due process given no reassessment mechanism?	Chamberlain argues lack of ongoing risk reassessment violates substantive due process.	State contends the statutory path for risk assessment and possible termination preserves due process.	Remanded for reconsideration in light of CSOT list.
