The Council on American-Islamic Relations' (CAIR) federal lawsuit seeks to block the state from enforcing an executive order that the Governor of Maryland, Larry Hogan, signed in October 2017.
The order requires contractors to certify in writing that they don't boycott Israel. The group's suit claims the order has an unconstitutional chilling effect on First Amendment-protected political advocacy supporting Palestine.
According to CAIR, 25 other US states have enacted measures similar to Maryland's, through legislation or executive orders. CAIR attorney Gadeir Abbas said other federal lawsuits have challenged measures in Arizona, Arkansas, Kansas and Texas.
CAIR sued Hogan and state Attorney General Brian Frosh on behalf of software engineer Syed Saqib Ali, a former state legislator. Ali's lawsuit says the order bars him from bidding for government software program contracts because he supports boycotts of businesses and organizations that "contribute to the oppression of Palestinians."
"Speech and advocacy related to the Israel-Palestine conflict is core political speech on a matter of public concern entitled to the highest levels of constitutional protection," the suit says.
Raquel Coombs, a spokeswoman for the attorney general's office, said the attorney general hadn't seen the suit and doesn't comment on pending litigation. A spokeswoman for Hogan's office didn't respond to an email and phone call seeking comment.
Ali, a resident of Gaithersburg, served as a member of the Maryland House of Delegates from 2007 to 2011 and represented Montgomery County as a Democrat. He accused Hogan, a Republican, of making an "end around" the Legislature by signing the executive order after lawmakers repeatedly rejected several "anti-BDS" bills targeting the Palestinian-led Boycott, Divestment and Sanctions (BDS) movement.
"This is unacceptable, and Larry Hogan should know that our rights will not be stricken by him," Ali said at a news conference in Baltimore.
The executive order says a boycott based on religion, national origin or ethnicity is discriminatory. A business boycott of Israel and its territories "is not a commercial decision made for business or economic reasons," it says.
"Contracting with business entities that discriminate make the State a passive participant in private-sector commercial discrimination," the order says.
In December, the Arkansas Times weekly newspaper filed a lawsuit to block a similar measure. That state law, which took effect in August 2017, requires contractors to reduce their fees by 20 percent if they don't sign a pledge not to boycott Israel.
Arkansas Attorney General Leslie Rutledge's office argued that boycotting Israel is not activity protected by the First Amendment.
"It is neither speech, nor is it conduct that is inherently expressive, nor associational activity that is afforded constitutional protection," wrote attorneys representing Rutledge's office.
