Recently, Argumentation Mechanism Design (ArgMD) was introduced as a new paradigm for studying argumentation among self-interested agents using game-theoretic techniques.Preliminary results showed a condition under which a direct mechanism based on Dung's grounded semantics is strategy-proof (i.e.truth enforcing).But these early results dealt with a highly restricted form of agent preferences, and assumed agents can only hide, but not lie about, arguments.In this paper, we characterise strategy-proofness under grounded semantics for a more realistic preference class (namely, focal arguments).We also provide the first analysis of the case where agents can lie.
