A write-in candidate and a group of citizens from South Jersey have expressed concerns over Ted Cruz's eligibility to appear on the ballot in New Jersey's June 7 Republican Primary.

A decision was expected on Tuesday following arguments from Victor Williams and the South Jersey Concerned Citizens Committee argued in front of Administrative Judge Jeff Masin on Monday that Cruz is ineligible to run for president because he was born in Canada, northjersey.com reports. Williams is an assistant law professor at the Catholic University of America.

Cruz's mother was born in Delaware and his father was born in Cuba. Cruz was born in Calgary, Alberta, Canada. In his defense, Cruz has argued that he is a "natural born" citizen because his mother is from Delaware, according to the report. Williams and the Concerned Citizens argue he is a naturalized citizen.

Masin has said the phrase "natural born" doesn't mean a person was born in the United States, according to the report. The U.S. Supreme Court has not resolved the issue of eligibility in presidential elections. Several challenges to Cruz's eligibility in other states have been thrown out because the challenger lacked standing, but Williams says his standing lies in the fact that he is a declared candidate for president in several states, according to the report.

He is on the ballot in nine states, but has done so for the sole purpose of challenging Cruz's eligibility, according to NBC News.

He said he is supporting Cruz's rival Donald Trump in the primary in states where Williams is not on the ballot, according to the Courier Post.
