Lobby group AfriForum is considering taking legal action regarding the expropriation of land without compensation, the organisation said in a statement on Sunday.
AfriForum's deputy CEO Ernst Roets said the organisation had notified Parliament in writing that it would be consulting its legal team regarding declaring Parliament's process to amend Section 25 of the Constitution to empower the state to expropriate property without compensation, as illegal.
Roets said this was after attempts by the Constitututional Review Committee to consult with the public regarding the amendment of Section 25 already had to "bid defiance to various procedural crises".
The committee will embark on its provincial tour to gain public input into the issue from June 26.
Roets claimed that it seemed to AfriForum that the process related to gaining the public's input had been manipulated from the beginning to reach an outcome that would support the ruling party's stance.
He said, "AfriForum has identified ten potential procedural irregularities that may have a substantial impact on the outcome of the process regarding the public hearings that have been organised for this objective and that already need to kick off in two weeks."
The ten issues include that many of the venues and times at which these public hearings will take place were still not known to the public.
The organisation said the agenda that would be followed was also not known.
"Contradicting lists with different dates and venues for these public hearings were published by the committee. It is clear that the venues that were chosen in which these public hearings will take place are mostly located within wards in which the ruling party has more support.
"Too few public hearings are being arranged, which would exclude a significant section of the South African population. The public hearings are organised within the vicinity of only a small section of the South African population," said Roets.
He said no security arrangements had been made public regarding the hearings.
