According to this news item of March 30, 2023 about Texas Senate Bill 18 - Public universities could no longer offer tenure for professors under Texas Senate bill | TPR - public universities in Texas would not be able to offer tenure to professors after Sept. 1.
If eventually signed into law by the governor, faculty in the University of Texas system who have tenure will retain it; but faculty who do not have tenure will not be able to apply because there will no longer be tenure.
Questions:
Is the opportunity and/or potential to get tenure contractable?
Do current faculty who have taught, published and worked towards tenure under the assumption they will be able to apply for tenure - do they have a case for breach of contract if the law goes into effect and they cannot apply for the benefits of tenure?
