A Washington, D.C. law firm that argues cases revolving around issues of religious freedom has gotten involved in an Iowa case. The Becket Fund for Religious Liberty has filed a brief arguing that religious organizations throughout Iowa would be bombarded with lawsuits if same-sex marriage is made legal in Iowa.

Six gay and lesbian couples are suing, asking the courts to toss out the state law which stipulates the only legal marriages in Iowa are those between a man and a woman. Lawyers for that group of gay couples argue that law is unconstitutional.

The D.C. law firm arguing against that contends Iowa’s courts will be flooded with lawsuits. For example, the Becket Fund for Religious Liberty argues ministers who preach against same-sex marriage might face "hate crime" charges, or churches that fire married gay employees might face anti-discrimination lawsuits.
