We examine a few graph classes of graphs and discuss the criticality of Perfect Italian Domination. We also define ?pI stable graphs and PID critical graphs. Following our definitions of ?pI-stable and PID critical graphs, we have grouped some graph classes. We characterise a family of trees that is ?pI-stable.. MatDer.
