We introduce a multi-agent system based on logic programming. In this system an agent has a knowledge base written in an extended logic program. Then, an agent performs default reasoning in the situation that her belief is possibly rebutted by other agents. We present a logical framework of such systems and also characterize the system in situation calculus.
