As one may readily observe, including Justice Daniel who left the Court in May 1860, Lincoln had only four Justices to replace. However, Lincoln appointed five justices.
With the appointment of Justice Field on May 20, 1863 the size of the Court swelled to 10 members.
One may observe that Justice Catron and Justice Wayne left the Court in 1865 and 1867. However, no appointments were made between December 1864 and March 1870.
TRANSLATION:
In 1863, at the critical time of the war, in order to ensure domination of the Court and prevent any negative decisions, the size of the Court was swelled to 10 members so Lincoln could pack it with another member.
While Andrew Johnson was President, it would appear that there were two vacancies he failed to fill. In fact, in order to keep its hold on the Court, and to prevent President Johnson from appointing anybody who might not share their thoughts on reconstruction and trampling upon the Constitution, in 1866 the radical-controlled Congress reduced the size of the Court to seven justices and provided that no vacant seats could be filled until that number was reached.
The actual number of sitting justices only fell to eight, but reducing the official number to seven was an insurance policy against President Johnson ever appointing anybody to the Court.
In 1869, with Republican U.S. Grant in office, the radical-controlled Congress restored the authorized size of the Court to nine members. In 1870, President Grant was able to appoint Justices Strong and Hunt to replace Justices Catron and Wayne who had left the Court in 1865 and 1867.
And THAT is how Supreme Court hokey-pokey was played by the radical-controlled Republican Congress.
It's ok the Republicans ate at Subway.
