The Tennessee Supreme Court reviews very few cases in a given year. In the year ending June 30, 2020 (the last period for which information is publicly available) the High Court was asked to accept review in 569 cases. (These are the cases where the Court has the discretion whether to hear the case or allow the lower court ruling to stand. There are other types of cases that the Court is required to hear.) Out of the 569 cases it was asked to review, it accepted only 20.
In the same fiscal year, the Court issued opinions in 63 cases.
Given the case selection criteria in discretionary review matters and the types of appeal-as-of-right cases, each opinion is highly likely to materially impact Tennessee law.
