Efremenko showed locally-decodable codes of subexponential length that can handle close to 1/6 fraction of errors. In this paper we show that the same codes can be locally unique-decoded from error rate 1/2 - α for any α > 0 and locally list-decoded from error rate 1 - α for any α > 0, with only a constant number of queries and a constant alphabet size. This gives the first sub-exponential length codes that can be locally list-decoded with a constant number of queries.
