Tomic had criticised Hewitt for playing himself in the doubles during Australia's Davis Cup World Group play-off loss to Australia last September.
Tomic,after his first-round Australian Open defeat,also accused Hewitt of favouring certain players.
He also said that Nick Kyrgios and Thanasi Kokkinakis also didn't want to play Davis Cup while the two-time grand slam champion was captain.
Hewitt in turn claimed Tomic had threatened his family and said that the former world No.17 wouldn't play Davis Cup under his watch.
