Liability laws are primarily determined by the state of Texas: negligence laws and Tort Claims Act. These bodies of law determine whether the city of McKinney can be held responsible for any accidents that occur on public land. However, there are other jurisdictions that may have rules and ordinances that can affect the ultimate responsibility for what occurred.
The county judge can issue court orders in certain situations. Those court orders could be evidence of negligence if they otherwise have an action against the county, a city within the county or against the private individual. In the same manner, an ordinance of the city can also serve as evidence of negligence.
Most cities in North Texas have ordinances that apply when there is to be construction of a pool, such as requiring it to be fenced. Additionally, the fence has to meet certain criteria, such as being gated so as to keep unsupervised children out.
Often, a local attorney may look at those ordinances and court orders to determine if there is evidence of negligence based on a violation of a court order or ordinance. If a lawyer determines that the city of McKinney failed to uphold the ordinances regarding fencing a public pool, for instance, they could use that as evidence in a premises liability case, provided the claim could meet the waiver requirements of the Texas Tort Claim Act.
