Former presidents of the league, including Malusi Gigaba and Fikile Mbalula, sit on the task team.
The crisis committee said it wanted the disbandment of the “purposeless stokvel of elders masquerading as youth leaders” as it was inconsistent with the ANCYL constitution, which gives its members powers to run the league.
It said it would serve the ANC with an interdict on November 6.
The ANCYL national executive committee (NEC) was disbanded in July 2019 and the task team was subsequently appointed to oversee the running of the league and convene an elective congress as a matter of urgency.
However, 15 months later, the task team has still not been able to organise the congress. Initially, it had earmarked May to hold the event but could not go ahead because of the coronavirus pandemic.
The task team said it was committed to reviving the youth league, which has been on a downward spiral since the expulsion of its former leader and now EFF leader Julius Malema.
Under Collen Maine the league failed to gain relevance with the youth of the country until its NEC was disbanded and the task team appointed to take over.
It was not immediately clear whether the crisis committee would still go ahead with its legal action after the announcement of the intention to finally hold the congress.
