Investors in struggling casino operator Star Entertainment (ASX:SGR) did their best to ignore the news yesterday that the company is being sued in the Federal Court by key financial regulator AUSTRAC over claimed breaches of money laundering laws over "a number of years". The shares ended up 0.3% at $2.71, after touching a low of $2.67 when it was made clear pending legal action from AUSTRAC had become something much more serious. While the regulator did not detail the allegations in a way similar it did for the Commonwealth Bank and Westpac, AUSTRAC did say in a statement it had launched civil penalty proceedings in the Federal Court against the Star for alleged systemic non-compliance with Australia's anti-money laundering and counter-terrorism financing laws.
