List of Argentine senators, 2003–2005
For the first time since 1973, all seats in the Argentine Senate were renewed in the 2001 legislative election, following the implementation of a new system as per the 1994 constitutional amendment.Under the agreed system, a third of all seats would be renewed for two years (2001–2003), a third for four years (2001–2005), and another third for six years (2001–2007).The term length was decided by draw.Accordingly, two thirds of the senators listed here were elected in 2001: one third for four-year terms (2001–2005) and another third for six-year terms (2001–2007).A third of the senators listed here were elected in 2003 for corresponding six year terms (2003–2009).
