Thanks to the Supreme Court’s decision in Facebook v. Duguid, 141 S. Ct. 1163 (2021), 2021 will go down as one of the most significant years in the history of the Telephone Consumer Protection Act, 47 U.S.C. § 227 (“TCPA”).  And while the second half of 2021 did not produce the fireworks that we saw earlier in the year, there are still some cases worthy of note as we enter the new year.  We summarize here developments since our last update, listed by issue category in alphabetical order.
