The author discusses previous work by Morley, Sacks, Harnik and Makkai on Vaught's conjecture. Using a generalization of Fodor's lemma for trees (in a narrow tree any stationary set of nodes has a stationary subset along one branch) he extends some of the known consequences and presents some new results on counterexamples of Vaught's conjecture which make use of admissibility theory.
