Law of Texas
The law of Texas is derived from the "Constitution of Texas" and consists of several levels, including constitutional, statutory, and regulatory law, as well as case law and local laws and regulations. Sources. The Constitution of Texas is the foremost source of state law. Legislation is enacted by the Texas Legislature, published in the "General and Special Laws", and codified in the "Texas Statutes". State agencies publish regulations (sometimes called administrative law) in the "Texas Register", which are in turn codified in the "Texas Administrative Code". The Texas legal system is based on common law, which is  interpreted by case law through the decisions of the Supreme Court, the Court of Criminal Appeals, and the Courts of Appeals, which are published in the "Texas Cases" and "South Western Reporter". Counties and municipal governments may also promulgate local ordinances. Constitution. The Constitution of Texas is the foundation of the government of Texas and vests the legislative power of the state in the Texas Legislature. The Texas Constitution is subject only to the sovereignty of the people of Texas as well as the Constitution of the United States, although this is disputed. Article I of the Constitution of Texas  contains the following provisions related to limitations on legislative power: Article II of the Constitution of Texas mandates the separation of powers in to three distinct department, the Legislative, Executive, and Judicial. Article III of the Constitution of Texas is specifically dedicated to the Legislative Department. Legislation. Pursuant to the state constitution, the Texas Legislature has enacted various laws, known as "chapter laws" or generically as "slip laws". These are published in the official "General and Special Laws of the State of Texas" as "session laws". Most of these statutes are codified. The Texas Constitution requires the Texas Legislature to  revise, digest, and publish the laws of the state; however, it has never done so regularly. In 1925 the Texas Legislature reorganized the statutes into three major divisions: the "Revised Civil Statutes", "Penal Code", and "Code of Criminal Procedure". In 1963, the Texas legislature began a major revision of the 1925 Texas statutory classification scheme, and as of 1989 over half of the statutory law had been arranged under the recodification process. The "de facto" codifications are "Vernon's Texas Statutes Annotated" and "Vernon's Texas Codes Annotated", commonly known as "Vernon's". The unannotated constitution, codes, and statutes can  also be accessed online through a website of the Texas Legislative Council. Gammel's "Laws of Texas" contains relevant legislation from 1822-1897. Most, but not all, Texas statutes have been codified in the following codes: Regulations. The body of regulations promulgated by state agencies is referred to as  administrative law. The "Texas Administrative Code" contains the compiled and indexed regulations of Texas state agencies and is published yearly by the Secretary of State. The "Texas Register" contains proposed rules, notices, executive orders, and other information of general use to the public and is published weekly by the Secretary of  State. Both are also available online through the Secretary of State's website. Case law. The Texas legal system is based on common law, which is interpreted by case law through the decisions of the Texas Supreme Court, the Texas Court of Criminal Appeals, and the Texas Courts of Appeals. There is no longer an officially published reporter. "West's Texas Cases" (a Texas-specific version of the "South Western Reporter") includes reported opinions of the Supreme Court, the Court of Criminal Appeals, and the Courts of Appeals. The "Texas Reports" includes Supreme Court opinions until July 1962, and the  Texas Criminal Reports includes Court of Criminal Appeals opinions until November 1962. Appellate opinions from 1997–2002 onwards are generally available online. There is no systematic reporting of decisions of trial courts. Online availability of case filings at the trial court level varies drastically: some district courts and county courts at law allow online access to download case filings, either for free or for a fee, either to registered users (sometimes restricted by attorney status) or to all users, whereas other trial courts only allow online access to the clerk's register of actions or the case docket, or no online  access at all. For example, the Harris County District Clerk's website requires users to register for free in order to download case filings. The Harris County Clerk similarly requires registration in order to download case filings, though the search function is available to unregistered users. In Dallas County, the District Clerk and County Clerk's records are available from a single online portal which allows for most non-sensitive case filings to be downloaded without registration. Filings from all 254 Texas counties can be searched by registered users for free through the statewide re:SearchTX portal, though a payment  of $.10 (ten cents) per page is required for downloads. Local ordinances. Municipal governments may promulgate local ordinances, rules, and police regulations, and are usually codified in a "code of ordinances". Counties in Texas have limited regulatory (ordinance) authority. Some codes are printed by private publishers, and some are available online, but the most common method of discovering local ordinances is by physically traveling to the seat of government and asking around. Age of criminal responsibility. Criminal courts in Texas have automatic jurisdiction over all persons over 17 years of age. there was advocacy to raise the age to  18. The Texas House of Representatives passed such a bill in 2017 that would be effective 2021. In August 2017 there were thirty-three prisoners in adult prisons and/or state jails who were below the age of 18. In Texas the minimum age at which a child may be adjudicated as delinquent is 10. Murder statutes. Capital murder convictions have two options: life imprisonment without parole and death. Prior to 2005 life with parole and death were the two options, but that year the Texas Legislature modified the statute. Maurice Chammah , author of "Let the Lord Sort Them: The Rise  and Fall of the Death Penalty", stated that governments of smaller counties supported the move as death penalty cases had increasing costs.
