The Maryland chapter of the Invisible Empire of the Ku Klux Klan reapplied yesterday for a permit to hold a "Support Your Police" rally in a Montgomery County park this Saturday. Two anti-Klan groups have separately applied for permits the same day.

John Hoover, a spokesman for the Maryland-National Capital Park and Planning Commission, said a decision on the Klan permit will be made on the day of the planned rally. Hoover said a decision will also be made Saturday on a permit request by the All People's Congress, one of the anti-Klan groups.

Decisions on rally permits for county residents must come within five days of the request. The Klan applied for the permit last week, but that permit was denied because the Klan leader who made the request was not a county resident. Nonresidents must give 30 days notice, Hoover said.

Another group, called the Montgomery County Citizens Against Hate, applied for a Nov. 6 rally permit last week, and Hoover said the decision on their permit will be made tomorrow. The Citizens Against Hate group was formed as a response to the Klan's proposed rally by former Democratic party chairman Stanton J. Gildenhorn, county NAACP director Roscoe Nix, and various civic and religious groups.

Klan Great Titan Samuel C. Royer, a Rohrersville (Washington County) resident who is about to be appointed Grand Dragon, said he called the Nov. 6 rally to show support for local police. Bill Wilkinson, national leader of the Invisible Empire, is scheduled to attend the Maryland rally and bestow the Grand Dragon title on Royer.

The Klan's permit was denied on Sunday, since Royer is not a Montgomery County resident. Yesterday, Hoover said he received another permit request from Michael Griffith, who listed a Gaithersburg address, gave his mother's telephone number, and listed his title as exalted leader. On the permit, he specifically requested the use of Wheaton Regional Park for the Saturday rally, beginning at noon.
