The Football Association faces the threat of legal action after announcing that results for the 2019-20 season will be expunged for non-league divisions below the National League and National League North and South.
The same applies to women's football below the Women's Super League and Championship, with no promotion and relegation, while grassroots football has been brought to a close for the season due to the coronavirus outbreak.
The FA's decision is particularly harsh on teams like South Shields, who were 12 points clear at the top of the Norther Premier Division, and chairman Geoff Thompson said the club will seek an appeal or take legal action.
In a message on Twitter, Thompson wrote: "SSFC will be writing to the FA in the strongest possible terms and will seek an appeal or will take legal action.
"Whatever the outcome following this appalling decision the club will continue as before. However, there is no denying this decision has a huge financial impact.
"We have invested heavily this year in a host of areas and the loss of promotion will also affect some of our revenue assumptions for next season.
My message to all our SSFC fans and sponsors is – sorry, a huge disappointment and we've all been badly let down."
The FA remains hopeful of being able to complete the men's and women's FA Cup campaigns, FA Trophy and FA Vase, while discussions are ongoing regarding what will happen with the National League, Women's Super League and Women's Championship.

"We need to secure the facilities. Not only the venues but the athletes' village, training sites and what not," Muto said.
"We need to assess whether they will be available when we need them next year. There will be additional costs that come with this – and we expect it will probably be massive.
"We are dealing with the postponement of the Games, which has never happened in history. The task is daunting."
