His father, the late Parkash Singh Badal, also a former Punjab Chief Minister, has been stripped of the Fakhr-e-Qaum (pride of the Sikh community) honour that was bestowed on him in 2011 for services to the community.
Wheelchair-bound Sukhbir Singh Badal and the core committee members as well as the leaders of the Akali Dal, who were cabinet members in 2015, will clean the bathrooms at Amritsar's Golden Temple on Tuesday from 12 noon to 1 pm.
After this, they will take a bath and serve langar.
The punishment came after Badal had tendered an unconditional apology to the Akal Takht admitting his mistakes.
Earlier in the day, the five high priests of the Sikhs, led by Akal Takht jathedar Giani Raghbir Singh, announced the quantum of 'tankhah (religious punishment for misconduct)'.
The jathedar asked the SAD working committee to accept Badal's resignation as party chief and for a panel to reorganise the party within six months.
Sukhbir Badal was declared a "tankhaiya" in August by Akal Takht after he was found guilty of religious misconduct "for mistakes committed by the party when it was in power in Punjab from 2007 to 2017".
The mistakes included the pardon of Gurmeet Ram Rahim for the sacrilege cases that had triggered clashes between Dera followers and Sikhs in parts of Punjab.
In 2007, Gurmeet Ram Rahim also dressed like the Sikh Gurus and performed a ceremony for which he was excommunicated by the Akal Takht. Sukhbir Singh Badal had allegedly used his influence to get the Dera chief pardoned.
