2026An ineffective assistance of counsel claim in a TPR case is analyzed under the two-part test set forth in Strickland v. Washington, 466 U.S. 668 (1984).

2026Justice was convicted, following a jury trial, of 2 counts of repeated sexual assault of a child, 2 counts of child enticement, and 2 counts of causing a child under the age of 13 to view/listen to sexual activity.1 The State argues that Justice’s trial counsel was not ineffective and that the circuit court erroneously applied the ineffective assistance of counsel analysis set forth in Strickland v. Washington, 466 U.S. 668 (1984). ¶2 We agree with the State and conclude that Justice’s trial counsel was not constitutionally ineffective.
