Only 53 percent of Koreans trust the Constitutional Court, a poll showed Friday.

Gallup Korea surveyed 1,100 Koreans aged over 18 nationwide between Tuesday and Thursday on how much they trust the six organizations related to Yoon's impeachment case: the Constitutional Court, police, court of justice, the National Election Commission (NEC), the Corruption Investigation Office for High-ranking Officials and the prosecution.

The poll showed that 53 percent of the respondents trust the Constitutional Court, while 38 percent expressed distrust over the country's highest court.

The survey comes amid escalating protests from Yoon's legal representatives and supporters, who have raised concerns over the progressive leanings of Constitutional Court justice Jeong Gye-seon and justice nominee Ma Eun-hyuk, both of whom were nominated by the opposition Democratic Party of Korea.

Among the six organizations, the prosecution scored the lowest, with only 26 percent trusting the institution, while 64 percent of respondents said they had no confidence in the prosecution.

This came after the prosecution decided not to immediately appeal the Seoul Central District Court's decision to grant Yoon's request to cancel his arrest.

Following the prosecution in the rankings was the Corruption Investigation Office for High-ranking Officials, which received 29 percent trust and a 59 percent distrust rate.

Meanwhile, the NEC, which has been mired in nepotism allegations, saw its credibility drop to 44 percent from January's 51 percent, while the distrust rate jumped to 48 percent from 40 percent.

"Public trust in the NEC has fallen mainly among moderate and conservative groups, which seems to be related to the recent revelation on preferential treatment of hiring high-ranking executives' children,” the pollster explained.

The police received a 48 percent trust rating and 41 percent distrust, while the judiciary garnered 47 percent trust and 41 percent distrust among survey respondents.

The poll has a margin error of plus or minus 3.1 percentage points with a credibility rate of 95 percent.
