2015 New York's 11th congressional district special election

In April 2014, Grimm was indicted on twenty felony charges, including mail and wire fraud, perjury, obstruction of justice, employing illegal immigrants, and conspiring to defraud the United States after it was found that he under-reported revenues and employee wages relating to a restaurant he owned. He surrendered to the police and was released on $400,000 bail.^[2] Vowing his innocence, Grimm continued his campaign for reelection,^[3] and defeated Domenic Recchia, the Democratic Party nominee, by 53%, Grimm's highest margin in his congressional career.^[4]

On December 23, 2014, Grimm pleaded guilty to one charge of felony tax evasion. All other charges were dropped as part of the plea bargain.^[5][6] Grimm indicated that he would not resign his seat.^[7] However, on December 30, Grimm announced that he would resign from Congress on January 5, 2015, rather than be sworn in for his elected term.^[8][9] According to the U.S. Constitution (I.2.iv), Governor Andrew Cuomo is legally required to call a special election to fill the seat, which under the terms of the New York Constitution is to be held within 70 to 80 days of his announcement.^[10] On February 2, Cuomo, who had given no indication of when he would call the special election for, said that he was "looking at it now" but didn't have a timeframe for setting a date.^[11] Staten Island Attorney Ronald Castorina Jr. filed a lawsuit on behalf of 8 Plaintiffs from Brooklyn and Staten Island, Republicans, Democrats, Independents, and Non-Enrolled parties, to force Cuomo to call a special election^[12] and on February 17, Judge Jack B. Weinstein of the United States District Court for the Eastern District of New York ordered Cuomo to either schedule the election or explain why he was delaying, or he would schedule the election himself.^[13] Cuomo's office replied that he would "announce the date" for the special election "shortly".^[14] On February 20, Cuomo announced that the election would be held on May 5.^[15]

As it was a special election, primary elections did not occur. The nominees were selected by local party leaders in Brooklyn and Staten Island .^[16]

Besides the Democratic and Republican parties, the Conservative, Green, Independence, Reform, Women's Equality and Working Families parties are qualified New York parties. Under the terms of electoral fusion, a candidate may be nominated by multiple parties.
