The organization said that the directives to banks amounted to meddling into the executive and the judicial powers by the National Assembly.
“Checks and balances should ideally help contribute to the rule of law and strengthening our democratic dispensation but if one branch of government grows too strong and overreaching the country might be in trouble,” it said.
In a statement on Sunday by SERAP deputy director, Timothy Adewale, the organization said that, “It’s an affront to our constitutional democracy for the National Assembly to turn itself into a tool for checkmating the country’s justice system, especially the prosecution of grand corruption.
“Rather than helping Mrs Jonathan’s desire to achieve justice for what she may consider to be violations of her human rights, such directives are doing exactly the opposite and politicising the criminal justice process.
“Nigerians are concerned about their lawmakers’ thirst for power, and about the National Assembly aggrandizing its legislative powers without sufficient checks and constitutional scrutiny and validity.
“The National Assembly ought to focus the exercise of its legislative powers solely on making laws for the peace, order and good government of our country, addressing only matters of prime national concern, and when necessary, checking the excesses of the executive branch.
“The directives purportedly unfreezing the accounts of Mrs Jonathan will not give the public the confidence that the National Assembly will change its ways and embrace the rule of law.
“The National Assembly should not show itself as incapable and unwilling to address the concerns of Nigerians about its operations and apparent lack of transparency. These kinds of interventions by the National Assembly could portray our lawmakers in the eyes of Nigerians as forgetting what they are in Abuja to do.
“The Senate and House of Representatives should advise Mrs Jonathan to seek appropriate judicial remedies if she feels the criminal justice mechanisms have violated her human rights. That’s the essence of the rule of law, separation of powers and checks and balances. The supposed directives to banks have unfortunately again put the reputation of the National Assembly at stake.
“What Nigerians want and deserve is a balanced sharing of constitutional powers for the sake of the public good, and not ‘Imperial National Assembly’, a National Assembly that sits on its throne in Abuja and treats Nigerians as serfs in their fiefdoms.
“If the body that makes law also controls its execution, implementation and interpretation, it can effectively tailor the laws to help itself and its friends and hurt its perceived enemies. It can thwart the virtue of impartial general law-making by rendering it a tool for singling out.”
The Senate had last week directed that Mrs Jonathan’s accounts in Stanbic IBTC, First Bank, Union Bank, Diamond Bank, Fidelity Bank, Ecobank and Bank Zenith Bank be unfrozen.
It claimed that the Economic and Financial Crimes Commission (EFCC) used the banks to close the accounts without due process of law.
The House of Representatives in September gave a similar directive to the banks to free the former first lady’s blocked accounts.
