Within these guidelines the Council vetoes candidates who are deemed unacceptable. The approval process is considered to be a check on the president's power, and usually amounts to a small number of candidates being approved. In the 1997 election, for example, only four out of 238 presidential candidates were approved by the council. Western observers have routinely criticized the approvals process as a way for the Council and Supreme Leader to ensure that only conservative and like-minded Islamic fundamentalists can win office. However, the council rejects the criticism, citing approval of so-called reformists in previous elections. The council rejects most of the candidates stating that they are not "a well-known political figure", a requirement by the current law.
