جج پر ضمان: فقہی قواعد اور پاکستانی قانون میں تطبیق

A judge should be honest,  transparent, free and fair. He should always respect law. The question arises that if a judge who disrespects law and makes unbalanced decisions: as a result of which people get affected then will he or she be penalized? The Ḥanafi Scholars opine that if a judge passes a wrong decision intentionally, he should be penalized from his own property. Because in Islamic jurisprudence, judiciary owns a supremacy over the masses and everyone irrespective of the position is equal and has to obey law. Whether he is a judge or a commoner, he has to follow the rules and regulations as prescribed by law. In practice, Pakistani judges are not held responsible for making a wrong verdict. Our judges make judgments on the basis of already manipulated evidence. A judge bars himself from the responsibility of collecting evidence. Similarly, if a judge has developed personal grudges with the criminal then the criminal reserves right of appealing the higher court where the decision is reviewed and rectified. In such situation, there is a compulsion between the legal maxim "وَالْأَصْلُ عَدَمُ الضَّمَان" and the Pakistani laws. However, Ḥanafi jurisprudence and Pakistani Laws are not in accordance with each other. This study concentrates upon the nature of punishment and tort to be applied on judges in case of making a decision based on falsehood. It is suggested that Pakistan’s Judiciary should be reread as that the already in-practice system does not comply with the standards of Islamic teachings.

Synthesis and Characterization of Novel Heterocycles: Pyrazoles, Dihydropyrimidinones, Iminothiazolidinones, Quinolinyloxy Oxa/Thiadiazolamines and Triazolones /Thiones and Study of Palladium 0 -Catalyzed Cross- Coupling Reactions

This thesis describes the synthesis of various classes of heterocyclic compounds like, pyrazoles, dihydropyrimidinones, iminothiazolidinones, quinolinyloxy oxa/thiadiazol amines and triazolones/thiones and in addition study of palladium(0)-catalyzed cross- coupling reactions. Michael addition of some substituted anilines to methyl acrylate in acidic medium afforded the methyl 3-(substituted anilino)propionates (96-104), which on treatment with hydrazine hydrate in methanol were converted into corresponding 3-(substituted anilino) propionohydrazides (105-113) in good yields. Microwave irradiation of the latter with pentane-2,4-dione afforded 1-(3,5-dimethyl-1H-pyrazol-1-yl)-3-(substituted anilino) propan-1-ones (114-122) under solventless conditions. A series of new 5-substituted thiobarbituric acid derivatives 5-acetyl-3-aryl-2-thioxo- dihydropyrimidine-4,6(1H,5H)-diones (133-140) were synthesized by cyclocondensation of 1-aroyl-3-arylthioureas with malonic acid in the presence of acetic anhydride. These compounds exist in equilibrium with their enolic tautomeric form 5-(1-hydroxy ethylidene)-3-aryl-2-thioxo-dihydropyrimidine-4,6-(1H,5H)-diones. Plausible mechanism for the formation of products was proposed. Compounds (133-140) were evaluated for their preliminary antibacterial activity against a representative panel of Gram positive and Gram negative bacteria and were found to exhibit promising activity towards the tested microorganisms using levofloxacin as the reference drug. Of these compounds, the derivative (134) having methoxy group at ortho position of phenyl ring showed the highest effect on pathogenic bacteria and was identified as the lead molecule for further structural modifications. An efficient, synthesis of some 1-aroyl-3-aryl thioureas (123-132) was carried out. Substituted aroyl chlorides were treated with an equimolar quantity of potassium thiocyanate in acetone to afford the corresponding isothiocyantes which were not separated followed by reaction with an equimolar amount of substituted anilines to furnish the 1-aroyl-3-arylthiourea derivatives (123-132) which were assayed in vitro for their antimicrobial activity against Gram positive and Gram negative bacteria and were found to exhibit moderate to potent activity towards the tested microorganisms, compared to the standard drugs Tetracycline, Penicillin and Metronidazole.An efficient, regioselective synthesis of some 2-aroylimino-3-aryl-thiazolidin-4-ones (141-150) involving base-catalyzed cyclization of 1-aroyl-3-aryl thioureas with chloroacetyl chloride in dioxane is reported. Compounds (141-150) were assayed in vitro for their antimicrobial activity against Gram positive and Gram negative bacteria and were found to exhibit promising activity towards the tested microorganisms, comparable to and in some cases better than those of the standard drugs. The cyclic condensation of 1-aroyl-3-aryl thioureas with dimethyl acetylene dicarboxylate (DMAD) in methanolic solution at room temperature resulted in the formation of methyl [4-oxo-2-(substituted benzoylimino)-3-(substituted phenyl) thiazolidin-5-ylidene] acetates (151-164) in good to excellent yield. The synthesis of bis(thioureas) was carried out by treatment of aroyl/alkyl chloride with potassium thiocyanate and as a result corresponding isothiocyanates were obtained using acetone as solvent. These isothiocyanates were treated with 1,2-phenylene diamine and 1,2-bis(thioureas) (165-172) were obtained in good yield. Similarly, these isothiocyanates were treated with 1,4-phenylene diamine and resulted in 1,4-bis(thioureas) (173-180) synthesis. These bis-(thioureas) were also treated with dimethyl acetylene dicarboxylate (DMAD) and corresponding 1,2-bis(iminothiazolidinone) acetates (181-188) and 1,4- bis(iminothiazolidinone) acetates (189-196) were synthesized in good yield. A series of quinolinyloxy oxa/thiasemicarbazide derivatives (200-207) were synthesized. Intramolecular cyclization of these quinolinyloxy oxa/thiasemicarbazide derivatives in the acidic medium of poly phosphoric acid (PPA) resulted in synthesis of quinolinyloxy 1,3,4-oxa/thiadiazolamine derivatives (208-215) while in basic medium of sodium hydroxide intramolecular cyclization of these quinolinyloxy oxa/thiasemicarbazide derivatives resulted in synthesis of quinolinyloxy 1,2,4- triazolones/thiones derivatives (216-223). A series of 1,2-difluoro-3,4,5,6-tetra substituted phenylbenzene derivatives (226-228) was reported through Suzuki-Miyaura coupling-reaction of 1,2-difluoro-3,4,5,6- tetraiodobenzene with various boronic acid derivatives using tetrakis(triphenyl phosphine) palladium(0) as catalyst. The substrate 1,2-difluoro-3,4,5,6-tetraiodobenzene (225) was also synthesized by treatment of 1,2-difluoro-benzene with molecular iodine in the presence of K2S2O8, trifluoro acetic acid and sulphuric acid.
