LATHROP – Dalwinder Dhoot can’t dispute the fact that Lathrop voters overwhelmingly supported a one-cent sales tax increase in 2012 – to the tune of more than 77 percent. But what the local business owner – who bought Joe’s Travel Plaza on Harlan Road in 1993 – does dispute are the claims that were made regarding the pressing need for the increase that officials have used to hire back police officers or retain firefighters since it went into effect in April of 2013. And he’s willing to take the matter to court.
