[1][2] Throughout the 1960s and 1970s the Davis Cup had been affected by a number of protests and defaults by teams showing their opposition to the apartheid policies and white minority rule in South Africa and Rhodesia, and the human rights violations which occurred in Chile under Augusto Pinochet's military junta.

[3][4][5] This show of political will in a sporting context was not welcomed by some, and for a brief time the United States, the inaugural winner of the cup, announced their decision to withdraw from the competition due to the apparent lenience of the tournament's organisers to prevent defaults by teams.

[6] In response to these withdrawals, the Davis Cup committee made a greater commitment to keep politics out of the competition.

The Soviet Union would have their entry rejected in 1978 after informing officials they would refuse to compete against South Africa.

Proposals were also brought forward to bring in an automatic one-year ban for any nation which pulled out of the tournament after the draw had been made, in an effort to prevent teams from defaulting on political grounds: [7] The United States, Great Britain and France all returned and competed in the 1977 tournament.
