President Tshisekedi formed a coalition with his predecessor
The Democratic Republic of Congo's President Felix Tshisekedi has pledged not to accept any reforms that undermined the independence of the judiciary.
The president said he would not back "reforms that would harm the fundamental principles governing justice".
There is a standoff within the ruling coalition over a proposal to give the justice ministry more control over criminal prosecutions.
Last week the justice minister was briefly arrested, prompting the prime minister to threaten the resignation of the government.
President Tshisekedi formed a coalition with his predecessor Joseph Kabila, who maintains extensive powers through his parliamentary majority and control of most cabinet ministries and the prime minister's office.
In an address to the nation to mark the Democratic Republic of Congo's 60th anniversary of independence from Belgium, Mr Tshisekedi affirmed his commitment to working with the coalition.
But "let me take this symbolic occasion of commemorating independence to reaffirm that no majority, political or parliamentary... can overstep the founding principles of the republic," he warned.
