This is how the CCEO phrases it:
{Canon 42} Just as, by the Lord’s decision, Saint Peter and the other Apostles constitute one college, so in a similar way the Roman Pontiff, successor of Peter, and the bishops, successors of the Apostles, are joined together.
{Canon 43} The bishop of the Church of Rome, in whom resides the office (munus) given in special way by the Lord to Peter, first of the Apostles and to be transmitted to his successors, is head of the college of bishops, the Vicar of Christ and Pastor of the entire Church on earth; therefore, in virtue of his office (munus) he enjoys supreme, full, immediate and universal ordinary power in the Church which he can always freely exercise.
{Canon 44} 1. The Roman Pontiff obtains full and supreme power in the Church by means of legitimate election accepted by him together with episcopal consecration; therefore, one who is already a bishop obtains this same power from the moment he accepts his election to the pontificate, but if the one elected lacks the episcopal character, he is to be ordained a bishop immediately. 2. If it should happen that the Roman Pontiff resigns his office (munus), it is required for validity that he makes the resignation freely and that it be duly manifested, but not that it be accepted by anyone.
{Canon 45} 1. The Roman Pontiff, by virtue of his office (munus), not only has power over the entire Church but also possesses a primacy of ordinary power over all the eparchies and groupings of them by which the proper, ordinary and immediate power which bishops possess in the eparchy entrusted to their care is both strengthened and safeguarded. 2. The Roman Pontiff, in fulfilling the office (munus) of the supreme pastor of the Church is always united in communion with the other bishops and with the entire Church; however, he has the right, according to the needs of the Church, to determine the manner, either personal or collegial, of exercising this function. 3. There is neither appeal nor recourse against a sentence or decree of the Roman Pontiff.
{Canon 46} 1. In exercising his office (munus) the Roman Pontiff is assisted by the bishops who aid him in various ways and among these is the synod of bishops; moreover the cardinals, the Roman curia, pontifical legates and other persons and various institutes assist him according to the needs of the times; all these persons and institutes carry out the task committed to them in his name and by his authority for the good of all the Churches, according to the norm of law established by the Roman Pontiff himself. 2. The participation of patriarchs and other hierarchs who preside over Churches sui iuris in the synod of bishops is regulated by special norms established by the Roman Pontiff.
