All eyes will be on the new Senate's role in the charter amendment process, particularly a proposal to amend Section 256 of the charter to allow for the drafting of a new charter.
It remains to be seen whether the move will succeed as it requires the support of at least one-third of the new 200 senators, or 67 members. Unlike their predecessors, the senators will not be empowered to co-elect a PM. They will take part in passing legislation and amendments to laws and the constitution.
They will also be authorised to endorse the appointment of members of independent organisations, Constitutional Court judges, and the Attorney-General as well as keeping the performance of the executive branch in check.
The term of the president of the Constitutional Court will expire in November this year, while seven of the nine court judges will also complete their tenure in 2027. The tenure of five of the current seven election commissioners will end next year.
