Former President Ram Baran Yadav has called for an amendment to the constitution to address the grievances of different communities.

Inaugurating the first International Tamu Conference in the Capital on Friday, Yadav, the first head of state after the country became a federal republic, urged the government and the major parties to correct the mistakes in the main law of the land.

The Constitution of Nepal was promulgated on September 20, 2015, amid serious reservations expressed by the indigenous and Madhesi communities. Yadav was president at that time.

Madhesi parties had even boycotted the constitution drafting process during its last phase in the Constitution Assembly.

“The constitution should be amended to ensure its broader acceptance. The mistakes in the constitution should be corrected without delay,” said Yadav. “The delay in the amendment will give rise to more dissatisfaction.”

The two-day conference has the participation of hundreds of people from the Gurung community residing worldwide.

Nepal marked the fourth anniversary of the constitution’s promulgation last month amid reservations from different communities. The Madhesis, Tharus and the indigenous communities are particularly unhappy in the manner the provinces were constituted.

“There could be complexities in the implementation of the constitution if there is a further delay in its amendment,” said Yadav.

The Rastriya Janata Party Nepal from the opposition and Samajbadi Party Nepal, which is a part of the incumbent federal government, have been demanding an amendment to the constitution.

The Upendra Yadav-led Samajbadi Party joined the KP Sharma Oli-led government after forging a two-point deal on May 28 last year. The deal included the party’s demand for an amendment to the constitution based on mutual understanding among the governing parties.

However, the Samajbadi Party hasn’t firmly pushed for a revision in the statute since joining the government.

The Rastriya Janata Party, meanwhile, has been persistent in its demand.

Leaders of the ruling Nepal Communist Party (NCP), including Prime Minister Oli, maintain that the constitution can be amended, only if it is necessary.

The first amendment to the constitution in January 2016 increased reservation quotas for the backward communities in government jobs. It also included a provision to delineate the constituencies based on the proportion of the population.

However, the Madhesi parties said that the amendments weren’t enough to address all of their grievances.
